Can we regard "lecture" as a monomorphemic word in Modern English?
Solution 1:
I think one can safely deem "lecture" as monomorphemic, as its etymology, by Etymonline.com, shows:
late 14c., "action of reading, that which is read," from M.L. lectura "a reading, lecture,"
As you can see, it comes from the Latin word lectura, which means that "lecture" is itself the root word, as its Latin root isn't something like lec or tur. This can be compared to other monomorphemic words, such as "wait" as well as "man"
