Definition of "majuscule"

Up to this point, Loveday appeared to be an exceptionally typical undergraduate, in that he wrote in majuscule what his fellows scribbled in lower case.

1951, Arthur Calder-Marshall, The Magic of My Youth, R. Hart-Davis, page 111

But it is far from impossible that a scribe writing in minuscule should choose majuscule for a correction at this point: for example, if he had written u for n the only way to avoid all misunderstanding might be to indicate the correction with a capital letter.

1972, Wiener Studien, H. Böhlaus, page 89

Many of these strips are palimpsest and bear earlier writing in majuscule and old minuscule.
