'tuberculostatic' is formed from Neo-Latin combining elements: 'tuberculo-' (from Latin 'tuberculum' meaning 'small swelling, tubercle') + '-static' (from Greek 'statikos' via New Latin meaning 'causing to stand, stopping or inhibiting').

'tuberculum' (Latin) → New Latin/medical combining form 'tuberculo-' + suffix '-staticus'/'-static' (from Greek/Latin scientific formation) → English 'tuberculostatic' as a modern medical term.

Originally built to mean 'stopping or acting on tubercles' in a morphological sense; it has come to mean specifically 'inhibiting the growth of the bacteria that cause tuberculosis' in medical usage.
