Morphology

fixation = fix (semi-transparent) = fix + ation

While 'fix' and 'ation' are clear, the specific meaning in histology is specialized and not immediately evident to all learners.

Etymology

Fixation comes from the verb fix, which means 'to fasten' or 'make firm'. In the lab, a fixation is like 'gluing' a tissue so its parts stay in place, which is why it preserves structure.
