The easiest solution seems to be to patch it to use offline dictionaries. merriamwebster.txt is 24MB, not a big deal.

stardict --install en_US hi_IN ta_IN

For a trilingual person, just 100MB of storage. Problem solved no?

Edit: it's a full dictionary with all sorts of information. Example entry:

ABANDONED A*ban"doned, a.

1. Forsaken, deserted. "Your abandoned streams." Thomson.

2. Self-abandoned, or given up to vice; extremely wicked, or sinning without restraint; irreclaimably wicked ; as, an abandoned villain.

Syn. -- Profligate; dissolute; corrupt; vicious; depraved; reprobate; wicked; unprincipled; graceless; vile. -- Abandoned, Profligate, Reprobate. These adjectives agree in expressing the idea of great personal depravity. Profligate has reference to open and shameless immoralities, either in private life or political conduct; as, a profligate court, a profligate ministry. Abandoned is stronger, and has reference to the searing of conscience and hardening of heart produced by a man's giving himself wholly up to iniquity; as, a man of abandoned character. Reprobate describes the condition of one who has become insensible to reproof, and who is morally abandoned and lost beyond hope of recovery. God gave them over to a reprobate mind. Rom. i. 28.
