Many speakers object to the use of momentarily in the sense of “in a moment” rather than “for a moment”, since this is inconsistent with the meaning of momentary;[1][2] nonetheless, this use is quite common in North America, and is particularly associated with airlines, such as “we will be landing momentarily”.[3][1][2] In place of momentarily, many speakers prefer the terms presently, soon[1][2] or the phrase “in a moment”,[2] for this sense of “in a moment”.
