Naming note
If Theodore has 3 syllables, try a middle with a different rhythm so the full name does not feel flat.
Use a classic middle if you want balance, or a rarer middle if the first name is already very popular.
Check initials, repeated sounds, and the transition between the last sound of Theodore and the first sound of the middle name.
Arthur, August, Oscar, Jasper, Louis, Henry, Otis, Walter, Felix, Arlo are strong options because they balance Theodore's sound and style.
Both can work. A short middle keeps the full name crisp, while a longer middle can make Theodore feel more formal or expressive.
Start with rhythm, then check meaning, initials, and whether the middle name makes the full name feel warmer, stronger, softer, or more distinctive.
