There's a teacher who's been helping 
us out and never left us behind,
،هنالك مدرّسة تساعدنا ولم تتخلَّ عنّا أبدًا
Unsere Lehrerin will uns nicht aufgeben
und nahm uns unter ihre Fittiche,
Hay una maestra que no se ha dado
por vencida con nosotras,
Hay una maestra que no se ha dado
por vencida con nosotras,
La professeure continue à nous aider
contre vents et marées,
C'è una professoressa che ci ha sempre aiutate, 
senza mai abbandonarci al nostro destino...
Tem uma professora que esteve nos
ajudando e nunca desistiu da gente,
Одна из учителей всегда
помогает нам и не бросает,
