So I think about name possibilities a lot; no babies for me in the near future. been pondering [name_f]Jacinta[/name_f] for a few months, and cannot for the life of me come up with a nickname other than maybe [name_m]Jack[/name_m] or [name_u]Jackie[/name_u]…help? Thanks guys 
[name_f]Jaci[/name_f] (sounds like JC)
[name_f]Cindy[/name_f] or [name_f]Cindi[/name_f]
[name_f]Cinta[/name_f]/[name_f]Cinda[/name_f] (Sounds pretty much the same in my accent honestly).
I like [name_f]Jacinta[/name_f] better with the Spanish pronunciation honestly, which kills [name_u]Jackie[/name_u].
[name_f]Cinta[/name_f], Cinty, Jinty, Jinta, [name_u]Jace[/name_u]
I have a cousin called [name_f]Jacinda[/name_f] who is nicknamed [name_f]Cindy[/name_f].
I think [name_f]Jinnie[/name_f], [name_f]Jin[/name_f], [name_f]Jinger[/name_f], [name_m]Cinna[/name_m]
My optometrist is named [name_f]Jacinta[/name_f] and her close friends just call her [name_u]Jesse[/name_u]. She is a mutual friend of my mom so that is how I know her nickname.
[name_u]Jess[/name_u] (if you say it Je-sin-tah), [name_f]Cinnie[/name_f], [name_f]Cinta[/name_f], [name_u]Jacey[/name_u] and [name_f]Cinda[/name_f] could be used I also know a [name_f]Jacinda[/name_f] who is called [name_m]Jazzy[/name_m] so [name_m]Jazzy[/name_m] or [name_u]Jazz[/name_u] could work
[name_f]Jacinta[/name_f] is pronounced hah-THEEN-tah (Spanish), hah-SEEN-tah (Latin American Spanish). I’ve never heard it proncounce with a J sound. I like [name_f]Tina[/name_f]/[name_f]Cinta[/name_f] for it, but would prefer no nickname.
[name_f]Giacinta[/name_f] would give you the ‘J’ sound.
