diction.

Diction, in its original, primary meaning, refers to the writer's or the speaker's distinctive vocabulary choices and style of expression.[citation needed] A secondary, common meaning of "diction" is more precisely expressed with the word enunciation — the art of speaking clearly so that each word is clearly heard and understood to its fullest complexity and extremity. This secondary sense concerns pronunciation and tone, rather than word choice and style.
Diction has multiple concerns; register — words being either formal or informal in social context — is foremost. Literary diction analysis reveals how a passage establishes tone and characterization, e.g. a preponderance of verbs relating physical movement suggests an active character, while a preponderance of verbs relating states of mind portrays an introspective character. Diction also has an impact upon word choice and syntax.
Diction comprises eight elements: Phoneme, Syllable, Conjunction, Connective, Noun, Verb, Inflection, and Utterance.

denotative and connotative

The denotation of this example is a red rose with a green stem. The connotation is that it is a symbol of passion and love - this is what the rose represents.

The denotation is a mosque. The connotation is a symbol of religion, according to the media connotation. However, to be more specific this is a symbol of Islam.

The denotation is a representation of a cartoon heart. The connotation is a symbol of love and affection, not in the way of a rose, but a symbol of true love.

the boolean search

Boolean searches allow you to combine words and phrases using the words AND, OR, NOT and NEAR (otherwise known as Boolean operators) to limit, widen, or define your search. Most Internet search engines and Web directories default to these Boolean search parameters anyway, but a good Web searcher should know how to use basic Boolean operators.
