Would you pronounce [name_f]Laetitia[/name_f] [name_m]Lay[/name_m]-tea-sha or [name_m]Lay[/name_m]-ti-tia? I hope you all understand my pronunciation guide, but basically, would you pronounce last syllable as -sha or tia?
[name_f]Do[/name_f] you know more simpler spelling/pronunciation (not [name_f]Lettice[/name_f])?
In [name_m]French[/name_m] it’s pronounced leh-tees-ya.
Most English speakers would probably pronounce it the same as [name_f]Letitia[/name_f] - luh-[name_f]TISH[/name_f]-uh or maybe luh-TEESH-uh in some cases.
