Questions about suffixes, a part of word between the stem and the ending. Some examples: "дом" -- "дом-ик" -- "дом-ишк-о" -- "дом-ищ-е", or "быстро"--"быстр-еньк-о".
Suffixes are morphemes that follow the stem and precede the ending and are used to derive words, for example, "дом" -- "дом-ик" -- "дом-ишк-о" -- "дом-ищ-е", or "толк-а-ть" -- "толк-ну-ть" -- "подтакл-ива-ть".
