"My daughters study at home."
Translation:Filiae meae domi student.
No accent aigu in Latin and æ is a late(r) invention originally not present in Latin. The ligature was only used in the late middle ages but by that time the sound ae stands for had changed.
Basicly it was usefull for scribes/monks to copy texts faster. You see it a lot in old english texts. (Again not representing the sound ae did in classical latin)
In the 16/17th century there was a big influx of Greek and Latin words, those loanwords were often transcribed with æ. (Like archæology)
