If you have an interest in English and the evolution of the language you must check out the YouTuber Simon Roper.
There's no finer student of the subject than him and I appreciate that he starts every video with "I am not [a] formally qualified linguist," yet he has a deeper understanding than most.
Some of my favorite videos:
- Celtic Influence on English [0]
- Progressing Some Words from Proto-Germanic to English [1]
- A London Accent from the 14th to the 21st Centuries [2]
- A Northern US Accent from the 18th to the 21st Centuries [3]
- Old English and Middle English; why are they so different? [4]
