meaning

[daisy1352]

Speak briefly, slowly and clearly.
What is the meaning of briefly? short or shortly?

I used big words and long sentences. Does big mean "not simple" here?
Thanks

In a way, yes, but more like, don't speak for a long time.

Speakers often use "big" to describe a word that isn't all that common; e.g., "...promulgating your esoteric cogitations, or articulating your superficial sentimentalities and amicable..." Source: Humor: Don't Use Big Words.

All the best.
