Good evening and welcome to Word of the Day! A journey through the English vocabulary and the words that piqued my interest, in WotD we'll be learning a new word for each working day of the week, bar holidays, unless there's a holiday special...

Today's word is:

abstruse

|abˈstro͞os|

Difficult to understand; obscure: An abstruse philosophical inquiry.

ORIGIN: late 16th cent.: from Latin abstrusus 'put away, hidden,' from abstrudere 'conceal,' from ab- 'from' + trudere 'to push.'
