A suffix consists of one or more letters added to the end of a word. Nouns, verbs, adjectives, prepositions, participles, infinitives and even some particles can take suffixes in Biblical Hebrew.
Biblical Hebrew utilizes four different types of suffixes. The most common type is the pronominal suffix which changes form based on both gender and number. However, there are also three other simple suffixes called the directional ה (he), the paragogic ה (he), and the paragogic נ (nun).
These suffixes should not be confused with the prefixes and suffixes that are added to finite verbs to form verbal conjugations, although certain forms appear very similar.
