# Are there any irregular groupings that are played in the time of a single beat of the same value?

I saw a source today where there were basically some questions and answers, as such:

Why use irregular groupings?

Why are triplets and sextuplets not considered an irregular grouping in compound time? **answer

There was this one question, which itself I don't have any problems with, since it's very simple in itself. However, it was worded quite weirdly: "Are irregular groupings always played in the time of a single beat of the same value?" Then they go on and explain how they [irregular groupings] are "not always" played in the time of a single beat of the same value, and summarize how that in simple time, quintuplets, sextuplets and septuplets are generally played in the same time as four notes of the same value. (there is much more, but I chose not to include it as this whole part isn't really relevant.)

My question is, based on the wording of the problem, specifically the "always" part in "are irregular groupings always played in the time of a single beat of the same value?" and the "no, not always" that is written in the answer, does that mean that sometimes they are? (As in, are irregular groupings sometimes played in the time of a single beat of the same value?) This leads to the question in the title.

So now, I'm curious as to whether the wording is just not clear and badly written or if there is such a scenario. (ty if you are willing to help~)

note: sorry if this is still hard to understand, I don't know if the way I wrote it is too "extra" or whatnot ^^
