Uzbek is an agglutinative language: suffixes are “glued” onto a word one after another, and each usually adds one meaning. The word ish-chi-lar-imiz-ga (“to our workers”) has five parts, each with its own job. So being able to break a word into its parts is the key to morphology: identifying the part of speech, the sentence part and the spelling all depend on it. The branch that studies word structure is morphemics, and the one that studies how new words are made is word formation. Exam tasks ask you to separate roots and suffixes, name the type of suffix and identify how a word was formed.
§1. Word structure: root, stem, affix
The root (o‘zak) is the part of a word that cannot be split into smaller meaningful parts and carries the main lexical meaning: ish, gul, o‘qi, oq. In Uzbek a root can be used as a word on its own. The stem (negiz) is the part an affix attaches to. It can be the root itself or a derived word:
ishchilar: root — ish, stem — ishchi (-lar is attached to precisely this stem)
An affix (qo‘shimcha) is a part added to a root or stem to give it a new meaning or a grammatical function. Uzbek affixes mostly come after the root; the few that come before it are mainly of Persian-Tajik origin: be-, no-, ser-, ba- (bebaho, notanish, sermahsul, baquvvat).
A morpheme is the smallest meaningful part of a word; roots and affixes are both morphemes
A simple way to find the root: remove the suffixes one by one from the end and stop when a meaningful, indivisible part remains.
§2. Three types of affix
Derivational (so‘z yasovchi) affixes create a new word with a new lexical meaning, often changing the part of speech: ish (noun) → ishla (verb), aql (noun) → aqlli (adjective), gul → gulzor (a flower garden — a new thing).
Form-building (shakl yasovchi) affixes add an extra meaning but neither create a new word nor link it to other words: the plural -lar, the comparative -roq, the diminutive-affectionate -cha, -jon, verb voices (yoz-dir, yoz-il), participle and converb forms (o‘qigan, o‘qib).
Inflectional (so‘z o‘zgartuvchi) affixes link the word to other words in the sentence: case endings (-ning, , , , ), possessive suffixes (, , ), personal endings of the verb (, , ).
Test: has a new word appeared that a dictionary would list separately? Yes — derivational. No, but has the word’s link to other words changed? Yes — inflectional. Neither — form-building.
Worked example
Identify the types of affix in ishchilarga (“to the workers”).
The root is ish (noun, “work”).
-chi: ishchi is a new word naming a person by occupation → derivational.
-lar: adds plurality without creating a new word → form-building.
-ga: the dative case, linking the word to a verb (ishchilarga berdi) → inflectional.
ish-chi-lar-imiz-ga: ish (root) + -chi (derivational) + -lar (plural) + -imiz (possessive) + -ga (case). This order is never broken: wrong ishlarchiga, kitobimlar (correct kitoblarim). The logic is simple: first a new word is made, then it is given an extra meaning, and last of all it is linked to the other words of the sentence. A word may contain several derivational affixes: ish-chi-lik, bil-im-don, paxta-kor-lik. Each creates a new word from the previous stem, so word formation proceeds step by step.
Worked example
Break down paxtakorlarimizning (“of our cotton growers”).
2. Compounding — creating a new word from two or more roots:
compound words: belbog‘, kungaboqar, toshbaqa, sotib olmoq (compound verb);
paired words: ota-ona, bola-chaqa, qozon-tovoq.
3. Conversion — a word moves to another part of speech without changing its form: yaxshi (adjective) → Yaxshidan ot qoladi (an adjective used as a noun). 4. Abbreviation — initial letters or parts are taken from a phrase: BMT (the UN).
An affix that looks the same can do different jobs: -cha forms an adverb in o‘zbekcha but a diminutive in kitobcha
§5. Types of word by structure
Simple underived (tub) word — no derivational affix, just the root: gul, bil, oq, tosh.
Derived (yasama) word — formed by an affix or by compounding: gulzor, bilim, oqlik, toshbaqa.
Single-root (sodda) word — one root: gul, gulzor.
Compound (qo‘shma) word — two roots, one meaning, written solid or separately: oshqozon, sotib olmoq.
Paired (juft) word — two equal words joined by a hyphen: ota-ona.
Cognates (asosdosh so‘zlar) — a family of words from one root: bil — bilim — bilimdon — bilimli — bildirish; o‘qi — o‘quv — o‘quvchi — o‘qituvchi. Knowing cognates also helps with spelling: an unclear sound can be checked with a related word.
Worked example
How was bilimdon (“knowledgeable, erudite”) formed?
The root is bil (verb, “know”).
-im is a noun-forming suffix: bilim (“knowledge”).
-don is an adjective-forming suffix: bilimdon (“having much knowledge”).
Formation in two steps: bil → bilim → bilimdon.
Answer: affixation; a derived single-root word.
§6. Order of morphemic analysis
When breaking a word into its parts, follow this order:
establish the word’s meaning in the sentence and its part of speech;
starting from the end, remove the inflectional suffixes (case, possessive, person-number);
then remove the form-building ones (plural, degree, voice, participle, converb);
check whether the remaining stem contains a derivational suffix; after removing each one a meaningful word must remain;
the meaningful, indivisible part left at the end is the root.
A word that is indivisible in the modern language counts as underived even if it was historically derived: qishloq (historically qish + -loq), o‘roq (o‘r- + -oq)
This order reduces mistakes: in o‘qituvchilik (“the teaching profession”), for example, you will see in turn o‘qi + -t (causative voice) + -uvchi (noun-forming) + -lik (noun-forming).

Common mistakes
Calling -lar derivational — it is form-building.
Confusing root and stem: in ishchilar the root is ish, the stem ishchi.
Breaking the order of affixes: wrong kitobimlar.
Treating a compound word as a phrase: belbog‘ is one word.
Not telling look-alike affixes apart: -cha may form an adverb or a diminutive.
Skipping formation steps: bilimdon comes not directly from bil but from bilim.
