של

Etymology 1
The possessed forms of של were a common construction seen also, for example, in 🇨🇬 and 🇨🇬. These were derived from the relative pronoun or prefix  in combination with the dative prefix, hence the Hebrew is equivalent to , thus “which [belongs] to”.

The first use of של as a possessive marker in Hebrew is attested in late parts of the Hebrew Bible, but then still preceded by, and in addition to, a possessive suffix (cf. Canticles 1:6; 3:7). In Mishnaic Hebrew, becomes a true preposition by back-formation. The standalone spelling is a more recent innovation, but the pronoun-including forms are unchanged (which may be seen both in their gemination of the ל, and in the unusual forms of the second- and third-person masculine and feminine plural pronominal suffixes, otherwise found only in the inflections of and ).

Preposition

 * 1) Of, belonging to, owned by, pertaining to.
