i think you have listen this word from a hindi song . you should go with complete lyrics then you can understand well!
lyrics is as follow -
Ek namkeen si baat hai, har nayi si baat mein Teri khusboo chal rahi hai jo mere saath mein(Now that your fragrance is Moving with me,There is a salty talk In your every new talk)
Halka halka rang beete kal ka, Gehra gehra kal ho jayega (The color of the past was light
While that of future will become dark)
Aadha ishq adha hai aadha ho jayega Kadmon se meelon ka wada ho jayega (Half a love is there
The remaining will happen A promise of miles to go Shall be made with the feet)
Here half love means a state of love where love is in initial stage . do not completely fall in love, just have only some attraction and feelings.
