inflectionally

The sound alternations may be used inflectionally or derivationally.

French has inflectionally distinct imperative, subjunctive, indicative and conditional mood forms.

In many languages, they are used to differentiate between otherwise identical lexemes, but in some they are used derivationally or inflectionally.

Basque is an ergative language, meaning that inflectionally the single argument (subject) of an intransitive verb is marked in the same way as the direct object of a transitive verb.

In some cases the tense is formed inflectionally as in English see/saw or walk/walked and as in the French imperfect form, and sometimes it is formed periphrastically, as in the French passé composé form.

In addition to being marked inflectionally in plural forms of nouns, gender is also selected for in the formation of verb stems; is marked in agreement in the inflection of verbs; and is realized in sets of pronouns.
