Word Meaning
देगी
degi
Meaning
Will give; (as auxiliary) will execute an action completely (feminine singular).
Detailed Meaning
In this couplet, 'देगी' functions as a separated auxiliary verb paired with 'जला' to form the compound verb 'जला देगी' ('will burn up'). It grammatically agrees with the feminine noun 'आग' (fire), predicting the total incineration of the lover's bones. Splitting and transposing the components of a compound verb is a classic rhetorical technique to heighten suspense and meet the meter.
Etymology
Derived from Sanskrit root दा (dā, 'to give') via Prakrit देइ (dei) into Hindustani देना (denā).
Usage
In classical Urdu ghazal, auxiliary verbs like 'देगी' are often displaced from the principal verb to maintain metrical rhythm and create dramatic tension.
Examples
This flame will burn the heart completely.
Hope will give life once again.
