As an example, in the words "simple and concise" and "concise", simple and concise is the correct word form. Correct word formation means that the word does not contain the wrong type of word.

The exact meaning of word forms varies greatly from language to language. For example, in English, word form change refers to the use of different forms of the same word in different contexts due to differences in person, tense, and mood; this is the use of word form change for the purpose of conveying meaning.

Introduction

Words can be categorized into two groups of 12 lexical forms; one group is real words: nouns, verbs, adjectives, number words, quantifiers and pronouns. One category is imaginary words: adverbs, prepositions, conjunctions, auxiliaries, exclamations and onomatopoeia.

The word form changes are: i. Nouns singular to plural; ii. Verbs in general tense to third person singular; iii. Verbs in general tense to past tense, past participle; iv. Verbs to present participle and so on.
