Erreur fréquente :

Synonymes
penetration (A more general technical term for going into something; in medicine, may be used for cells or substances entering tissue.)
Antonymes
containment (Describes keeping disease cells from spreading beyond their original site, the opposite of invasion.)
Collocations
