To provide praise that is so lukewarm it essentially implies criticism.

इतनी कमज़ोर तारीफ करना कि वह आलोचना के समान लगे।

English Usage: The manager damned the new employee with faint praise, noting that he had "some potential" but not elaborating further.

Hindi Usage: प्रबंधक ने नए कर्मचारी की फीकी तारीफ की, यह कहते हुए कि उसमें "कुछ क्षमता" है लेकिन आगे कुछ नहीं बताया।
