Morphology
biramous = ramous (semi-transparent) = bi + ramus + ous
The prefix 'bi-' clearly signals 'two', but the base 'ramous' (branched) is a technical/rare term, so the overall structural relation is only partly obvious to average learners.
Etymology
The word biramous comes from the parts bi- 'two' and ramus 'branch', so it literally means 'two-branch' and you can think of bi- as in bicycle for 'two'. That's why biramous describes a limb or part that is split into two branches.
