{qoch} is not the word for "partner" when referring to socks and gloves and the like.  The word for that is {nelwI'}.  With {nel}, the subject is one sock (or glove or shoe or whatever) of the pair and the object is the other.  To talk about a sock (or glove or….) matching (that is fitting onto) a foot (or hand or…), use the verb {mey}:

        {mumey waqmeywIj} "my shoes fit" (literally, "my shoes fit me")

        {torgh lumey waqmey}  "the shoes fit Torg"

        {waqmeywIj vImey}  "I fit my shoes"

        or

        {nelchu' Qay'mol teSra'} "the puzzle piece fits perfectly"

The first focuses on the interlocking of the pieces; the second focuses on the piece in question occupying the identically shaped space where it goes.
