Delight

delight about party putting out pair of lines (7)
the answer is of course overjoy, however, i simply have no idea how it parses. would some kind soul please enlighten me?
many thanks in advance

over(about) + jo(ll)y (party)

[Mamyalynne]

About- Over
Party putting out lines - Jo(ll)y

[JJ109]

over = about + jo(ll)y (party - lines)

[Toorak]

Over (about) jo(ll)y (party - jolly minus l l - 2 lines)

thank you danny kay mamyaly, jj and toorak, now that you have explained it seems obvious i did not equate about = over, i had thought of jolly for party but did not think of subtracting the lines. i suppose i must have had a blind spot. many thanks again to all of you for your kindness.
