Meet in sisters' home briefly, with sweetheart (7)

I believe the answer is:

convene

I'm a little stuck... Click here to teach me more about this clue!

'meet' is the definition.
(I know that convene is a more specific form of meet)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for convene that I've seen before include "Gather (for meeting)" , "Call together" , "rally" , "Meet formally" , "Three-legged stand" .)

I've seen this clue in The Irish Times.
