The most common noun form is the use of the two or three letter root. From the parent root ba (AB), meaning a tent pole, comes the noun (av) meaning "father". As was mentioned previously, all nouns are action oriented and the full understanding of the noun is "the one who holds up the tent/house". Just as the tent pole supports the tent, the father supports the family within the tent. The root (PTHh) is the base for the verb (patahh) meaning "to open" and the noun (petahh) meaning a door.

Additional nouns are also formed out of the base root by adding specific letters as prefixes, infixes and suffixes, in specific places within the root. The noun derivative (maph'teach) meaning a key is formed by adding the letter m to the front of the noun (petahh - a door). Some of the most common noun derivatives are formed by placing a (m) or t(t) before the root or a (i) or (o or u) within the root.

In Hebrew all nouns are either masculine or feminine. In most cases the nouns and noun derivatives are masculine and are converted into feminine nouns by adding one of four suffixes; (ah), (et), (owt), or (iyt). Generally, masculine nouns are concrete while feminine nouns are abstract.

Additional noun derivatives are formed by combining different prefixes, infixes and suffixes. The four feminine suffixes can also be added to any of the other noun derivatives resulting in a wide variety of possible nouns.

Nouns are made plural by adding the suffix or . Generally the is used for masculine nouns and for feminine nouns. In some cases masculine words, usually very ancient words, will use the suffix. The Hebrew words (av - father) and (or - light) are masculine words but are written as and in the plural. In all modern languages the plural is always quantitative while in Ancient Hebrew a plural can be quantitative or qualitative. For instance the word "trees" refers to more than one tree (quantitative) while in Hebrew the plural word (etsiym - trees) can mean more than one tree (quantitative) or one very large tree (qualitative). An example of this is the word (behemot or usually transliterated as behemoth in Job 40:15). This word is the plural form of the singular (behemah), meaning beast, but refers to a very large beast rather than more than one beast. One of the most common uses of the qualitative plural is the word (elohiym) which can be translated as "gods" (quantitative) or as "God" (qualitative).

Hebrew uses nouns for other functions within the sentence. They can be used as adjectives, adverbs, prepositions, conjuctions, etc. The noun (eqev) can be the "heel" of the foot but, it can also mean "because" in the sense of being on the heel of the previous phrase. Because the Ancient Hebrew language does not make distinctions between these types of words the Lexicon lists them all as nouns and noun derivatives.
