Final answer:
The word 'truancy' carries a negative connotation, referring to unauthorized absence from school, whereas 'sustain' has a positive or neutral connotation, and 'zealot' may be negative depending on context. 'Phenomenon' is neutral.
Step-by-step explanation:
Considering the definitions and contexts of the provided words, the word that carries a negative connotation is truancy. The word truancy refers to the action of staying away from school without good reason and is generally viewed negatively because it implies laziness or a lack of responsibility. On the other hand, sustain typically holds a positive or neutral connotation, suggesting support or maintenance over time. The word zealot may carry a negative connotation as well, depending on the context, as it refers to someone who is fanatical and uncompromising in pursuit of their religious, political, or other ideals. Phenomenon, however, is neutral, simply describing an observable event or a remarkable person.
Connotation and denotation are important linguistic concepts where the emotional implications (connotation) can differ significantly from the literal meanings (denotation) of words. For example, words like brainwashing carry a negative connotation, contrasting with the more neutral term teaching. Conversely, diverse tends to have positive connotations in our current cultural context, despite its denotation of simply being varied.
