formal = form (semi-transparent) = form + al

The meaning still relates to 'form' as structure or symbolic arrangement, but the mathematical and scientific use is technically specialized.

Etymology

Formal The word formal comes from Latin forma 'form', the same root we see in formula. So in maths and science 'formal' means using a fixed 'form' of symbols and strict rules.
