There are several suffixes in Hebrew that are appended to regular words to introduce a new meaning.
Suffixes are used in the Hebrew language to form plurals of nouns and adjectives, in verb conjugation of grammatical tense, and to indicate possession and direct objects.
[1] The letters which form these suffixes (excluding plurals) are called "formative letters" (Hebrew: אוֹתִיּוֹת הַשִּׁמּוּשׁ, Otiyot HaShimush).
Due to noun-adjective agreement rules, these apply to nouns and to adjectival modifiers.
These suffixes (Hebrew: סוֹפִית sofit) often come from loanwords from English (Latin, Greek, etc...) which are especially prevalent with technical and academic terms.
