The one-word verb daresay, meaning (1) suppose or (2) presume to say, is obsolescent despite its usefulness. But if you must use it and don’t mind its archaic ring, avoid following it with an unnecessary that, and make sure it’s used in the first person.
Examples
For example, that could be removed from these sentences:
… I daresay that his Fantasy is the most perfect album of the year. [TV Overmind]
I daresay that Wayne Rooney`s problems this season aren`t entirely related to his international exertions … [Vital Football]
I daresay that most recent immigrants and sons and daughters of immigrants embrace this country because so many left war torn regions of the world and cherish the peace and safety and lack of belligerence Canada offers. [Tandem]
For some reason, many authors are reluctant to use the one-word daresay, which has a long history in English. In these examples, the two-word dare say could be condensed to daresay:
I dare say mustard plasters would change sports medicine even in our modern era. [Times Herald]
But I dare say it’s the basic assumption of all modern theories of culture. [First Things]
