The meaning of Duaa is supplication for Allah. You can recite Duaas in any language. Allah accepts all of your duas in whatever language you speak to Him.
The Holy Prophet (peace be upon him) said: This is a month, the first of which brings Allah's Mercy, the middle of which brings Allah's forgiveness and the last part of which brings emancipation from the hell fire".{Bukhari} whatever language you speak to Him.
The second ten days (11-20) of Ramadhan are the days of Forgiveness.
So we should seek Allah's forgiveness and repent for sins in those days.
*Allahum- magh-fir-li dhunoobi Ya Rabbal Alameen
*Rabbana Fagh- fir- lana dhunoobana wa kafir-'anna sayyi- aatina wa ta-waf-fana ma-'al abraar.(Surah Al-Imran:193)
Meaning; Our Lord! Forgive us our sins and rent us our evil deeds, and make us die in the state of righteousness along with Al- brar (those who are obedient to Allah and follow strictly His Orders).
~Amin Yarabil Alaamin~
