Learn Italian: Seguo spesso lo sport. - I often follow sports.

The dictionary form (infinitive) is seguire (to follow). It is a regular -ire verb. To make the "I" form, you drop the -ire ending and add -o, giving you seguo.

Why is spesso placed after the verb instead of before it?

In English, we usually put "often" before the verb ("I often follow"). However, in Italian, adverbs of frequency like spesso generally go right after the verb. So, the literal sentence order is "I follow often...".

Why does this sentence use lo instead of il for the word "the"?

The word sport starts with an "s" followed by another consonant ("p"). As a rule in Italian, masculine words that start with an "s + consonant" combination always use the definite article lo instead of the standard il.

The English translation says "sports" (plural). Why is it singular (lo sport) in Italian?

When talking about the general concept of sports, Italians use the singular lo sport. While the plural gli sport exists (used when talking about various specific types of sports), you use the singular when saying you generally follow, like, or play sports.
