“Upper-case” is to “capital” as “lowercase” is to what?

Question

Is there a corresponding word to go with capital to mean lower-case?

Answer 1

There are capital letters and small letters.

In a formal or technical context I would use "lower-case" to avoid seeming like a young child talking about big letters and small letters.

Answer 2

In typography and calligraphy the corresponding terms are majuscule and minuscule:

See the Wikipedia entry on Capital letters. Minuscule also serves as the counterpart of capital.

Answer 3

For this analogy question, small is the word you are looking for:

uppercase : capital :: lowercase : small

small (adj): lowercase

Answer 4

Minuscule is also the word for them, although I doubt most people would know what you were talking about.

Answer 5

No, there is no equivalent (Like Pedi-Letter or something "Foot" related instead of "Head" related.)

You have the following options

1. lowercase
2. lowercase letter
3. minuscule
4. small letter

Although I do not recommend 3 unless you are amongst typographers, nor 4 (you will sound childish).
