From Middle English entren, from Old French entrer, from Latin intrō (“enter”, verb), from intrā (“inside”). Has been spelled as "enter" for several centuries even in the United Kingdom, although British English and the English of many Commonwealth Countries (e.g. Australia, Canada) retain the "re" ending for many words such as centre, fibre, spectre, theatre, calibre, sombre, lustre, and litre.
The verb is transitive and takes a direct object. When used for physical movement, it does not require the preposition 'into'.
