Morphology

thymidine = thym + idine

The components 'thym' and 'idine' are not standalone English words, and the meaning related to DNA is specialized and not transparent to learners.

Etymology

The word thymidine comes from thymine, a DNA base first found in the thymus 'gland', and the ending -idine is the same as in adenosine, showing it is a 'nucleoside'. So thymidine is the thymine part joined to a sugar, which is why it is a component of DNA.
