With examples define the following 1.morph 2.allomorph?

1. Morph: A morph is the smallest meaningful unit of language, typically a word or a part of a word that cannot be divided into smaller meaningful parts. For example, in the word "unhappiness," the morphs are "un-" meaning "not," "happy" meaning "feeling or showing pleasure or contentment," and "-ness" meaning "state or quality of."

2. Allomorph: An allomorph is a variant form of a morph that has a different phonological shape but the same meaning. Allomorphs can occur due to phonological rules or morphophonemic alternations in a language. For example, in English, the plural morpheme can be realized as "-s" in words like "cats," "-es" in words like "buses," or "-en" in words like "oxen." These different forms of the plural morpheme are all allomorphs.
