Etymology
the word 'sermon' entered english in the late 12th century from the old french 'sermon', meaning 'speech, discourse, or church homily'. the old french term derived directly from the latin 'sermo', which meant 'discourse, talk, or conversation'. this latin noun itself originated from the verb 'serere', meaning 'to join or link together', metaphorically extending to the linking of words in speech. the semantic journey reflects a narrowing of meaning from general conversation to a formal, often religious, discourse intended for moral instruction.
Analysis
this word is a simplex loanword from latin via old french. it is not productively formed from smaller, recognizable english morphemes.
