One of my mother's favorite conversational pastimes was pointing out errors in common language usage. Such expressions as "I could care less" amused her because the speaker meant to say "I couldn't care less." Now, there is an excellent website devoted to this topic -- no,not the topic of my mother's conversational interests, but the topic of COMMON ERRORS IN MODERN ENGLISH

In fact, I don't lend you money either because I have none to lend. Bob Dylan didn't sing, "please don't feel so all a lend." In truth, loan may be used as a verb. It is okay. It is also okay to eat chicken with your fingers, much as it is okay to eat chicken with mayonnaise.
