I cannot distinguish these words!

Hi there.

Dictionary.com gives you several definitions from several online dictionaries. Try it out. It also uses your word in example sentences, and it often lists origins and synonyms.

Inter- is a prefix that stands for "between."

To interrupt is to stop or bother.
To interfere is to meddle.
To intervene is to come between.

You see how interrupt and interfere can sometimes be perceived as "rudeness." That's why they usually have negative connotations. Intervene is more neutral (and sometimes positive, like you said).

Sprout and germinate are similar terms.

Hi there,

"Interfere in" and "interfere with" mean the same thing. If in doubt, use "interfere with", as it is more commonly used.
