Which is the correct spelling: 'The U.S. has 100 [Senaters / Senators / Senotors] in Congress.'

SENATORS is on the USCIS WRITING VOCABULARY list under CIVICS. Correct spelling: 'S-E-N-A-T-O-R-S.' The ending is '-ators' (a-t-o-r-s), NOT '-aters' (no 'e'). Note: many English nouns ending in 'or' (senator, actor, doctor) are commonly misspelled with 'er' (sometimes correct for some words but not these). Common dictation sentences using 'Senators': 'There are 100 Senators in Congress.' 'States have Senators.' 'Senators meet in the Senate.' 'The President meets with Senators.' CAPITALIZE 'Senators' when referring to U.S. Senators as a specific group (though casual usage may not always capitalize — the USCIS list shows it capitalized).
