In Inuktut, the basic units of meaning are roots, affixes and grammatical endings.
| niri- | to eat | 
| aullaq- | to depart; leave town | 
| tupiq | tent | 
Roots that describe nouns (people, places, animals or objects) sometimes appear on their own:
| nuna | land | 
| inuk | an Inuk; a person | 
| natsiq | ringed seal | 
Generally, though, words are built in Inuktut by attaching affixes and endings to a root.
Here are three simple noun endings:
| -mi | in / at a place | 
| -mut | to a place | 
| -mit | from a place | 
We can add these endings to a noun root to create a word:
| sijjami | at the shoreline | 
| sijjamut | to the shoreline | 
| sijjamit | from the shoreline | 
Verb endings are attached to verb roots that describe actions.  Here are three simple verb endings:
 
| -tunga | I | 
| -tutit | you | 
| -tuq | she / he / it | 
If we add different endings to the same root, we get different meanings:
| aullaqtunga | I am departing. | 
| aullaqtutit | You are departing. | 
| aullaqtuq | He / she is departing. | 
Affixes are pieces of words that appear between the root and the ending. They can never begin a word. Affixes add more information about the noun or verb that is described by the root.
For example -lauq- is a verb affix that indicates that an action happened in the past:
| aullalauqtunga | I departed. | 
| aullalauqtutit | You departed. | 
| aullalauqtuq | He / she departed. | 
In Inuktut, it is possible to build up very long words by adding a series of affixes between the root and the ending. We can end up with single words that would take an entire sentence to say in English:
qangatasuukkuvimmuuriaqalaaqtunga I’ll have to go to the airport.
