HALO ARCHIVE / SANGHEILI / LANGUAGE GUIDE
“Wort” means “go” in the English-to-Sangheili cipher created for Halo: Reach. That familiar battle cry is also the easiest entry into a system that turns English words, letters and sounds into the alien speech of Halo’s Elites.
The cipher shared in Halo Waypoint’s Canon Fodder: Heart and Soell gives fans a practical reference for examining short Sangheili phrases. It combines special vocabulary with substitutions such as TH → P’ and S → SH. Some examples can be reconstructed directly; others reveal choices that the key does not fully explain.
This guide preserves the supplied mappings and phrase samples, then shows how to use them without turning uncertain guesses into supposed canon. Its scope is the Reach cipher. Applying it to every alien inscription, name or line of dialogue across Halo would require evidence beyond this reference.
What this translation guide can do
Use it to recognise supplied phrases, follow straightforward English-to-Sangheili substitutions and explore possible readings. The material does not provide a complete grammar, a pronunciation guide or a reliably reversible dictionary. Several English letters share the same output, and some sounds have alternative forms.
Start with the phrases provided alongside the cipher
These nine pairings are the reference examples. Keep their spellings intact when quoting them. They are stronger evidence for those particular phrases than a fresh attempt to generate them from individual letters.
| English phrase | Sangheili sample |
|---|---|
| Look up there | Si’r ’wach p’umu |
| Go look ahead! | Wort si’r ua’uk |
| Yes, good! | Wir, wort’k |
| Go to safety | Wort pi shukupee |
| More heretics! | Mamu a’umupersh! |
| Me see one! | Pa sho’ imu! |
| Wake up! | Zuru ’wach! |
| Excellent, my skills are! | Udarusump shressh! |
| Enjoy this do I | Umrifa p’esh ki |
Apostrophes are retained as part of the supplied spellings. Capitalisation has been preserved in the samples; the cipher tables use capitals for easy comparison.
The English-to-Sangheili cipher
The key mixes three kinds of entry: complete words, paired letters and individual letters or sound cues. Keeping those groups separate makes it easier to see why a simple alphabet swap will sometimes fail.
1. Special word mappings
| English | Sangheili |
|---|---|
| SAFE | SHUKU |
| UP | ’WACH |
| MEAL | YAR (Yar) |
| GO | WORT |
| ME | PA |
| MORE | MAMU |
Check these entries before attempting letter substitutions. GO → WORT and ME → PA are demonstrated directly in the supplied phrases. The SAFE → SHUKU entry also helps explain the beginning of shukupee, the form paired with “safety”.
2. Paired-letter substitutions
| English pair | Sangheili output |
|---|---|
| EE | O’ |
| LL | S |
| OO | I’ |
| SS | ’SH |
| TH | P’ |
Treat these as candidate units before splitting a word into individual letters. For example, the OO in “look” uses I’, while TH in “this” uses P’. This is a useful working method drawn from the examples, rather than a complete published rule for every possible overlap.
3. Letters and sound variants
| English letter or cue | Sangheili output |
|---|---|
| A | U |
| B (“buh”) | R’ |
| C | R |
| D | K |
| E | U |
| F | K |
| G | A’ |
| H (“hh”) | A’ |
| H (“hew”) | AN |
| I | E |
| J | R |
| K | R |
| L | S or SH |
| M | P |
| M (“mmm”) | AM |
| N | M |
| O | I |
| O (“oh”) | A |
| P (“ph”) | CH |
| R (“rrr”) | W |
| R | M |
| S | SH |
| T | P |
| U | W |
| U (“uhh”) | ’WA |
| V | Z |
The supplied list has no standalone entries for Q, W, X, Y or Z. It also gives alternatives for L and several sounds. The parenthetical cues, including “buh”, “hew” and “mmm”, are reproduced as supplied; they do not amount to a complete system of phonetic notation.
How to use the key, step by step
- Check whether the complete phrase already appears in the reference samples. If it does, use that attested form.
- Look for special vocabulary such as GO, ME, MORE and SAFE. Do not assume these English letter sequences should be replaced wherever they occur inside unrelated words.
- Identify paired letters such as OO, EE and TH before considering individual letters.
- Apply the remaining mappings in order, retaining apostrophes and noting alternative sound choices.
- Compare the result with the supplied examples. Label newly constructed phrases as your own cipher renderings, and leave unsupported letters or choices unresolved.
Worked examples: where the substitutions line up
LOOK → SI’R
Split the word into L + OO + K. Choose the listed S form for L, then apply OO → I’ and K → R.
L + OO + K → S + I’ + R → SI’R
This matches Si’r in “Look up there”. Choosing SH for L would produce a different result, so the sample resolves that choice here.
THERE → P’UMU
Use TH as a pair, followed by the ordinary E, R and E entries.
TH + E + R + E → P’ + U + M + U → P’UMU
Combine LOOK → SI’R, the special UP → ’WACH entry and THERE → P’UMU to reconstruct the full sample: Si’r ’wach p’umu.
ME SEE ONE → PA SHO’ IMU
ME uses its special mapping, PA. SEE becomes S + EE → SH + O’. ONE becomes O + N + E → I + M + U.
ME / SEE / ONE → PA / SHO’ / IMU
The result matches the supplied phrase exactly, apart from capitalisation and punctuation.
Where automatic translation breaks down
The examples expose limits that a useful guide needs to preserve. “Yes” is paired with Wir, but the table supplies no Y mapping. “Wake” is paired with Zuru, despite the absence of a W entry. These are known phrase forms whose construction cannot be recovered fully from the listed rules.
“Good” presents another puzzle. A straightforward G + OO + D substitution gives A’I’K, whereas the sample gives wort’k. Its resemblance to GO → WORT is interesting, but the key does not establish a general rule that explains the whole result. Preserve the sample without inventing a missing rule.
The longer pairing “Excellent, my skills are!” → Udarusump shressh! also resists a simple word-by-word alignment. The reference gives the meaning of the complete line; it does not explain how every English component corresponds to the two written Sangheili units.
Can you decode Sangheili back into English?
Sometimes context and a known sample make a reading clear. A unique reversal is often impossible, however, because several English inputs collapse into the same output.
| Sangheili output | Possible English inputs |
|---|---|
| U | A or E |
| R | C, J or K |
| K | D or F |
| M | N or the ordinary R entry |
| P | M or T |
Those collisions create ambiguity even before considering word boundaries and multi-letter outputs. Begin with recognised vocabulary and complete phrases, then test possible readings against the scene. Reversing a substitution mechanically does not establish what an unfamiliar sentence means.
What does “wort, wort, wort” mean?
Within this Halo: Reach key, WORT maps to GO. Repeating that entry gives the straightforward cipher reading “go, go, go”. The reference supports that correspondence; it does not, by itself, document the production history or intended meaning of every similar sound heard elsewhere in the series.
Are the apostrophes pronunciation instructions?
The key does not define them that way. They appear in entries including I’, O’, P’, R’ and ’WACH, so they should be retained when copying or constructing a form. Assigning every apostrophe a particular pause, stress or throat sound would go beyond the information supplied.
The lasting value of this cipher is the view it gives us into how Reach made familiar battlefield instructions sound alien. “Look up there” becomes Si’r ’wach p’umu through a sequence we can follow. Where that sequence stops being clear, the remaining uncertainty is part of the reference, too.
