An insinuation or suggestion may be as effective as plain speech, especially when the listener is perceptive to such hints.

इशारा भी काफी होता है जब इंसान समझदार हो।

English Usage: He didn’t say he needed help, but a nod is as good as a wink to a blind horse, so I lent him a hand.

Hindi Usage: उसने मदद माँगी नहीं, लेकिन समझदार इशारा समझ लेता है, इसलिए मैंने उसकी मदद कर दी।
