English can be tricky in small, sneaky ways.
Sometimes the problem is not grammar rules or verb tenses. Sometimes it’s just one tiny letter.
Take this simple family word:
Should you write granddad or grandad?
Many English learners stop and think, “Which one is correct?”
Some dictionaries show both. Movies use both. Books use both. Even native speakers mix them up.
That can feel confusing.
You might worry:
- Is one wrong?
- Is one British and one American?
- Does one sound childish?
- Which one should I use in exams or writing?
These questions are very normal.

By the end of this guide, you will clearly understand:
- the meaning of each word
