Core Pattern

Sentence Pattern Overview

It + be + adjective + (for + person) + to + verb

Example: "It is easy for children to forget the steps."

📚 The 4 Grammar Rules

Rule 1: Stating importance, ease, or usefulness

To say that an action is important, easy, hard, safe or useful, start with it + be + adjective + to + verb. The word "it" has no real meaning of its own because the action is the real subject. Always put "it" at the start of the sentence.

• It is useful to keep a small towel in your bag.

• It is safe to drink this water.

Rule 2: Naming the person

To say who does the action, put for + the person right before "to". Never drop the word "for" in front of the person. Keep the order clean and clear.

• It is hard for young children to scrub for a long time.

• It is easy for children to lather soap on both hands.

Rule 3: Using negative words

A negative word can go in two places: not after be makes the adjective negative, and not before to makes the action negative. Choose the right spot for "not" depending on what you mean.

• It is silly not to dry your hands after you rinse them.

• It is not difficult to learn the steps.

Rule 4: Verb form rules

After the adjective, always use to + base verb. Never use an "-ing" form after the adjective. The verb after "to" has no extra "-s" ending.

• It is necessary to rinse the soap off well.

• It is easy to forget the steps.

⚠️ Common Mistakes to Avoid

❌ Incorrect:

"Is safe to drink..." (missing "it")

"It is necessary washing..." (using -ing)

✅ Correct:

"It is safe to drink..."

"It is necessary to wash..."
