Morphology

histochemical = chemical (semi-transparent) = histo + chemical + histo

Formed by adding the technical combining form 'histo-' (tissue) to 'chemical'; the structure is clear to learners familiar with scientific combining forms but 'histo-' is not a common standalone English word.

Etymology

The word histochemical comes from the parts histo- meaning 'tissue' and chemical meaning 'related to chemistry', so it describes methods that look at the chemicals inside cells and tissues.
