How do you pronounce it?
señor is pronounced /seˈɲoɾ/, with the stress on the last syllable, a ny sound in the middle and a tapped r at the end.

Do not pair señor with a first name the way you might say Mr. John. Use it with a surname or on its own. Also note that señor alone can sound more formal or distant than English sir in some situations, so tone matters.
