Looking for baby names that feature the letter-pair OO?
I’ve collected oodles of OO names for you in this post!
Before we get to the names, though, let’s get one big question out of the way…
What sound does OO make?
In today’s English, OO commonly makes the sound you hear in the words boot, food, and moon. But it can also make other sounds, such as the ones you hear in the words blood, or door, or good.
Why all this diversity?
A lot of it has to do with the Great Vowel Shift, which lasted from the late 14th century until about 1700. The GVS was a major factor in the transition from Middle English to Modern English.
In Middle English, OO tended to make a “long o” sound. (As one of my sources explained, “scribes often indicated a long vowel sound by doubling the vowel letter.”) So, in Middle English, the words boot, food, and moon sounded more like “boat,” “foad,” and “moan.”
During the Great Vowel Shift, the pronunciation of most long vowel sounds inexplicably shifted “upward” in the mouth, and the words boot, food, and moon acquired their present-day pronunciations.
But it’s not quite as simple as that. Because some words underwent multiple pronunciation changes during the GVS, while others didn’t undergo any change at all.
And this resulted in OO having a variety of pronunciations in Modern English.
Now, back to the names!

The name Brooklyn comes from the name of the New York City borough, which was founded by Dutch settlers in the 17th century and named after the Dutch town of Breukelen. The town name (originally “Broecklede”) can be traced back to the Middle Dutch words broec, meaning “marshland,” and lede, which referred to a dug watercourse (as opposed to a natural one).

(The Middle Eastern and Asian names — because they’re being transcribed from non-Latin scripts — can also be spelled other ways, such as “Behrouz” and “Purnima.”)
