Synonymy of postpositions and suffixes
The same meaning can sometimes be expressed both by a postposition and by a suffix. For example, the suffix -dek gives the meaning of likeness, and in this respect it is synonymous with the postpositions kabi, singari, yanglig‘: muzdek sovuq — muz kabi sovuq (cold as ice). The dative suffix -ga, in the sense of direction, comes close to the postposition tomon: bekatga yurdik — bekat tomon yurdik (we walked to/toward the bus stop). Synonymous forms help to avoid repeating the same word in a text and to express a thought in varied ways. However, since there are shades of difference between them, they cannot always replace each other.
Replacement contest: two groups race to replace phrases with “-dek” by “kabi” or “singari”.
