The Britons had a very slender knowledge of fortification.

My slender knowledge of the voyage is derived partly from John's laconic letters, partly from conversation after his return.

As a result of occasional maritime visits, the slender knowledge gained by these great navigators appears a remarkable omission.

Just as, without some slender knowledge of its former culture, we must be for ever ignorant of its inherited powers and aptitudes.

I am convinced that Mrs Piper, on her arrival in England, brought with her a very slender knowledge of English affairs or English people.
