The Pronoun-to-Verb Derivation Suffix لا|لە
ئالماشتىن پېئىل ياسايدىغان «لا|لە» ئارقا قوشۇمچىسى
Adding to the suffix لا|لە's versatility is its ability to couple with some of the personal pronouns (namely, سەن and سىز) to form the verbs that carry the meaning of "to address formally (with سىز)" and "to address informally (with سەن)". These are two verbs that English does not have, since both the formal and informal cases use a single "you".
