lībertīna f (genitive lībertīnae) Freedwoman question on the macron usage or similar words

I have a question about this word. However, I am not super familiar with Latin and no matter how much research I do, I can not seem to find something in a similar language that would translate to "freedwoman" the same way. My main question is, is this written
"lībertīna" or "libertina" I have seen it written with and without the macrons and want to make sure I do not do it incorrectly.
Also, if you know of words in other languages that translate the same way I would love to know...
