Grundlagen der Wortstellung

One of the first surprises in Latin is that word order is flexible. Because the endings on nouns and verbs already show who does what, the words can be arranged for emphasis without changing the basic meaning. Still, there are strong habits worth knowing so that sentences read naturally.

The common tendencies are:

Element	Usual position
Subject	near the start
Object	before the verb
Verb	often at the end

So a plain sentence tends to run Subject - Object - Verb: Puella rosam amat. - The girl loves the rose. But Rosam puella amat and Amat puella rosam mean the same thing; the endings, not the order, tell you that puella is the subject and rosam the object.

For English speakers: English relies almost entirely on order - "The dog bites the man" and "The man bites the dog" mean opposite things. In Latin, meaning rides on the endings, so canis virum mordet and virum canis mordet both say the dog does the biting, because canis is the subject form and virum the object form. The practical lesson: do not read Latin strictly left to right expecting the first noun to be the subject. Read the endings first, find the verb (often waiting at the end), and only then assemble the English.
