The act or process of composing or putting together; composition.
From compose plus the suffix -al (meaning 'the act of'). A rare or archaic term that has largely been replaced by 'composition' in modern English.
Composal is such a rare word that most spell-checkers don't recognize it, but it once meant the exact same thing as composition—seeing how English selected one word over another tells us about how languages naturally favor clarity and conciseness!
