technically speakking yes because ur parents are legally responsible for both?? if not she still is considered ur sister
No because your mother would have to give birth to herself. HOWEVER, if a biological mother died, an older sister could legally become the adoptive mother to her younger sister.
she likes my sister : elle aime bien ma sœur she is like my sister : elle est comme ma sœur
Actually, it's not phrased "sister mine", that I know of.Instead, the French say ma sœur (my sister).The online Google translator will show you how to pronounce sœur.
une sœur
Où est ta sœur ? -
"demi-sœur"
well if you can prove ur in a relationship with ur sister, I'm sure u can be added to the lease
ma belle sœur et nièce (only my sister is beautiful) mes belles sœur et nièce (they are both beautiful) note that "belle-sœur" in French sounds exactly the same, and means sister-in-law. A French speaker hearing this will certainly think of your sister in law.
A sister-in-law is "une belle-sœur" in French. The same word is also used for a step-sister.
you can but ur sister may not like it Personally i would do it anyway but i dont favor my sistor much sistor=sister+monster
no not unless she is ur best friend!! sorry!
