Edward II only spoke no English at birth. By the time he was a youth, I am sure he was perfectly fluent. (There is no direct evidence that Richard I, Cœur de Lion, raised in Norman castles in England, spoke English. He composed poems in Latin and Occitan, but none in English that have come down to us.)
“Edward II only spoke no English at birth.”
Lol. Neither did you or I.
“(There is no direct evidence that Richard I, Cœur de Lion, raised in Norman castles in England, spoke English.”
Richard Coer de Lion died in 1199. If you measure the birth of English as a language from the writing of the Canterbury Tales in 1387 (or was it 1400?), there was no English to speak in 1199, nor in the days of Edward II. There was an informal mish-mosh of Norman French and Saxon German along with a few other languages, but no body of literature as of yet.
