Morphology
decussate = decuss + ate
The combining form 'decuss' is not a recognisable English word and the meaning 'to cross in an X-shape' cannot be reliably derived by average learners from known English components.
Etymology
Decussate comes from the Latin root decuss-, linked to decem meaning 'ten' and the Roman sign for ten 'X', so to decussate is to cross or meet so they form an 'X' shape.
