If you've ever tried to look up a Kyrgyz verb in a dictionary, you probably know the pain.
You want to say "I work." You open the dictionary, look up "to work," and see the word иштөө. Your brain says: "Okay, so 'I work' must be мен иштөөймүн?" Nope. The correct form is мен иштеймин. The stem is иште. Where did the "е" come from? Where did the "өө" go? And how are you supposed to conjugate a word when the dictionary gives it to you in that form?
There are clear answers to all these questions — and they're simpler than they seem. The dictionary form иштөө = stem иште + suffix -үү (which merged into -өө). It's the stem that all the tense and person endings attach to.
Let's work through the system.
🧠 The dictionary's main secret
I want to make an important disclaimer upfront. I'm not a linguist and I don't claim academic authority. What's described below is the result of my own experience learning the language, analyzing hundreds of words, and trying to find a coherent system in them — because I never came across this kind of explanation in official textbooks. My goal is to share my perspective and maybe make your life a little easier.
Dictionaries always give verbs in the form of a verbal noun (infinitive): баруу (going/to go), жасоо (doing/to do).
But to build sentences, give commands, make requests, or change tenses, you need the base form (уңгу) — which is also the imperative mood form (бар, жаса).
At first glance it looks like four different suffixes — -уу, -үү, -оо, -өө — get slapped onto the base form in some random order. But if you dig deeper, there are really only two base suffixes: -уу and -үү.
Everything else is the result of sounds merging together. Let's see how this works in practice.
🧮 The transformation from stem to dictionary form
Rule 1. The standard case: stem ends in a consonant
If the verb stem ends in a consonant (or the letter й), you simply add the following suffixes:
| Stem vowels | Suffix | Example |
|---|---|---|
| Back vowels (а, о, у, ы) | -уу | бар + уу = баруу (to go) |
| Front vowels (э/е, ө, ү, и) | -үү | кел + үү = келүү (to come) |
Phonetic note: For smoother speech, if the stem ends in the voiceless consonants к or п, sound assimilation kicks in — they shift to their voiced counterparts г and б:
- чык → чыг + уу = чыгуу (to go out)
- тап → таб + уу = табуу (to find)
Exception: If two consonants appear in a row (a cluster), voicing doesn't happen: корк + уу = коркуу (to be afraid).
Rule 2. Where -оо and -өө come from
What happens when the stem already ends in a broad vowel (а, е, о, ө)? When the suffixes -уу / -үү attach to these stems, the vowels merge into a single long sound:
| Final vowel | Merger | Example |
|---|---|---|
| А | а + уу → оо | жаса + уу → жасоо |
| О | о + уу → оо | ойно + уу → ойноо |
| Е | е + үү → өө | иште + үү → иштөө |
| Ө | ө + үү → өө | сүйлө + үү → сүйлөө |
So -оо/-өө are the result of a merger, not separate suffixes.
💡 Memory trick: The broad vowel "absorbs" the narrow part of the suffix and stretches: А+УУ→ОО, Е+ҮҮ→ӨӨ. One principle — two different outcomes!
Rule 3. Where do narrow vowels disappear? (ы, и, у, ү)
If the stem ends in a narrow vowel (ы, и, у, ү), it simply gets "swallowed" when the suffix is added:
| Example | Transformation |
|---|---|
| оку + уу | окуу (one "у" dropped) |
| байы + уу | баюу ("ы" dropped, "й" + "у" became "ю") |
| ташы + уу | ташуу ("ы" disappeared) |
❗ Exceptions (Micro-verbs)
The two-letter verbs же (to eat) and де (to say) form their verbal noun differently — using the suffix -ш: жеш, деш.
Fun fact: if же- merged by the regular rules, you'd get жөө — which already means "on foot." And if де- merged the same way, you'd get дөө — which means "giant"!
💡 How to "unpack" a word from the dictionary
Now that you have this logic in your head, you can try deriving the stem for any dictionary word on your own:
- See -УУ / -ҮҮ? Just drop it: баруу ➔ бар.
- See -ОО? There's most likely an "а" hiding there: суроо ➔ сура, жашоо ➔ жаша, жасоо ➔ жаса. Less commonly, just drop one о.
- See -ӨӨ? There's most likely an "е" hiding there: иштөө ➔ иште, эсептөө ➔ эсепте. Less commonly, drop one ө — e.g., төлөө ➔ төлө.
If you're left with a voiced г or б at the end — apply the assimilation in reverse: тигүү ➔ тик, табуу ➔ тап.
And if the word feels too short, a narrow vowel may have dropped out: окуу ➔ оку.
I hope that after reading this article you'll be able to unpack these words automatically in your head. But if you're still unsure, ran into a tricky exception, or just want to double-check yourself — you can always use the conjugation tool.
