❌This bag is weightless' (when it is just not heavy).
✅This bag is very light.
💡weightless means zero or near-zero effective weight, not simply 'not heavy.'
❌The scientist studied weightless animals.
✅The scientist studied animals in a weightless environment.
💡the adjective describes the condition or feeling, not the animal itself as a permanent quality.
