Locate, settle.
1. He located his house there (not located there).
2. He settled in Chicago.
Loan, lend.
It is not incorrect to use loan in the sense of lend, but lend is the less formal and the preferable word.
May, can.
May it not be said that any person who has not learned the difference between these two words, can hardly be permitted to call himself a user of good English?
It is not hard to see why people confuse these two words. Often the questioner feels that, for all practicable purposes, the refusal of his request will make a barrier over which he cannot go. When he says “Can I go,” he is feeling, “Will you make it possible for me to go? for unless you consent I cannot go—I cannot afford to, or I cannot conscientiously, or I cannot and remain on right terms with you.” Nevertheless, may is the only right word to use in asking permission.
