Eloquent

Fits when charm and verbal persuasion deserve a vivid, informal label

Careful The phrase can imply slickness or manipulation, making it unsafe for sincere praise.

Fits when polished speech and good phrasing are enough

Careful It can praise accent or manners and may not indicate a powerful message.

Fits when feeling or personality comes through vividly

Careful Strong expression may be nonverbal or loosely structured rather than verbally accomplished.

Fits when emotional impact matters more than verbal craft

Careful A simple gesture or halting speech can be moving without being eloquent.

Fits when ideas are expressed clearly and precisely

Careful Clear explanation need not be graceful or persuasive, so it may undersell an eloquent speaker.

Fits when language flows smoothly and with easy command

Careful Fluency can be technically smooth without insight, emotional force, or persuasion.

Fits when the communication changes minds or motivates action

Careful Persuasion can rely on pressure or selective facts and does not guarantee elegance.

Fits when difficult material becomes unusually easy to understand

Careful Clarity alone is cooler and less affecting than eloquence.
