As part of our series on tricky word pairs, this post will introduce 4 word pairs/groups that can be confusing and misleading. We will first go through each pair thoroughly to clarify their specific definitions and usage. At the end of the post, we will have a revision practice for you to test your knowledge.

1. Disinterested VS Uninterested

Disinterested: unbiased, impartial

Uninterested: not interested; not having feelings or mind engaged

 2. Extenuate VS Attenuate

Extenuate: to lessen the seriousness of an offence by giving reasons
The court judged that the woman’s repeated theft of food is extenuated by her poverty and the hunger of her young child.

Attenuate: to reduce the force or value of something

 3. Averse VS Adverse VS Avert VS Aver

Averse: strongly disliking
While the Catholic Church is generally averse to same-sex marriage, the local priest explicitly expressed his support for the recent marriage equality campaign.

Adverse: preventing success, harmful
Despite adverse conditions such as drought and lack of sunlight, the plants flourished in their new environment.

Avert: to turn away; to prevent

Aver: to declare positively

 4. Effete VS Effuse VS Effect

Effete: having lost strength or vitality [from Latin effetus (usually in fem. effeta) “exhausted, unproductive, worn out (with bearing offspring)]
After centuries of intermarrying, the aristocracy of Europe had grown effete.

Effuse: to flow out [from Latin effusus “poured out,” past participle of effundere “pour forth, spread abroad; to lavish, squander, waste”]
His friend effused great joy after receiving his gifts and kind words.

Effect: a change which is the result of a cause [from Latin effectus “accomplishment, performance” from past participle stem of efficere “work out, accomplish]

*Some students confuse effect and affect. To affect is to have an effect on something; for example, cold temperatures have a negative effect on my energy as they affect my ability to sleep well at night.
