I am reading Pierre Deligne's paper La conjecture de Weil : I.
In this paper he takes a general enough linear subspace $A$ of codimension $2$ of a projective space $\mathbb{P}$ (see page 290 in the french version) which translation in frech is "sous-espace linéaire de codimension $2$ assez général", so I am wondering how I should understand the adjetive "General enough"? Thank you in advance for your help!
