Ah, a bit of linguistic trivia, I see!

It's true that there are four Rs in the word "strawberry," which is a bit unusual for an English word. This is because the word "strawberry" actually comes from the Old English word "streawberige," which meant "stray berry." Over time, the word evolved to its current form, with the extra Rs sticking around.
Interestingly, the plural of "strawberry" is not "strawberries" but "strawberrys," with the Ys replacing the Rs in the plural form. This is because the word "strawberry" is treated as a compound word, rather than a regular noun with a plural ending in "-ies."
