Morphology
The constituents 'form' and 'family' give a clear clue that this is a grouping based on form, so a learner who knows both words could infer it refers to a kind of classificatory group. However, the specific technical sense—an artificial taxonomic category (ranked between order and genus) and its specialized usage—cannot be fully predicted from the parts alone, making the expression only partially transparent to a B1 learner.
Etymology
Form family comes from the idea of grouping animals or plants by their form, meaning their 'shape' or 'look', when scientists are 'not sure' how they are really related. The word family simply means a 'group', so form family is a 'temporary' group made because members look alike rather than because we know they belong together.
