“I made a decision to go to the celebration.”

“I used to be compelled to eat the greens.”

A break up infinitive happens when “to” and the verb are separated. For instance:

“I made a decision to not go to the celebration.”

“I used to be compelled to sadly eat the greens.”

These sentences can simply be “fastened” by rearranging the phrases (eg. “to not go”, “sadly to eat”). It is considerably controversial whether or not or not break up infinitives are thought-about to be correct grammar. They are pretty widespread in speech and may typically assist to cut back ambiguity in a sentence, however some strict grammarians nonetheless think about them to be grammatically incorrect.
