i hope to find clear information contrast between inflectional and derivational with analysis
  

Top answer

1) Derivation often changes the word's lexical category, but not always: great (adjective) => great+ly => greatly (adverb) dog (noun) => dog + house => doghouse (noun) 2) Inflection doesn't change the word's lexical category. It adds meaning: number, person, tense: Number: dog (singular noun) => dog + s => dogs (plural noun) Person: walk (present verb) => walk +s => walks (3rd person present verb) Tense: walk (present verb) => walk + ed => walked (past tense verb) 3) Derivation occurs close to the word, whereas inflection occurs outside the derivation: Derivation: dog (noun) => dog + house => doghouse Inflection: doghouse (singular noun) => doghouse + s => doghouses (plural noun) Ungrammatical: dogs + houses => *dog s houses Above, inflectional -s is added to a noun, and then another noun "houses" is added to that. The result is ungrammatical.
