INDISCREET vs TALKATIVE: ADJECTIVE

Lacking discretion
Synonyms Imprudent, unwise, injudicious, inconsiderate, rash.
Not discreet; wanting in discretion or prudence; not in accordance with sound judgment.

Synonyms Talkative, Loquacious, Garrulous. Talkative is a mildly unfavorable word; the others are clearly unfavorable. Talkative is applied to a person who is in the habit of speaking frequently, whether much is said at one speaking or not: thus, a lively child may be talkative. A loquacious person is one who has this inclination with a greater flow of words, and perhaps a disposition to make many-words of a small matter. Garrulous is the word applied to mental decline, as in old age, and implies feeble, prosy, continuous talk, with needless repetitions and tiresome details. The subject of a garrulous person's talk is generally himself or his own affairs or observations.
Inclined to talk or converse; ready or apt to engage in conversation; freely communicative; chatty.
