The cause is simple: neo-latin native speakers choose among words they are familiar with. In english many not so frequent, scientific, studied or intellectual ones comes from latin or even greek ones(as in this case).

The result is that even a person who has not studied english (well, some months some decade ago..) and that make many ugly basic mistakes can produce sentences with a studied appearence to the ear of a native english speaker.

This is an intersting phenomenon.

familiar, studied (adj.), intellectual, person, decade, phenomenon are examples where a native english probably would choose a different rooted word coming from old english or ancient germanic.
