The Sentence

Yes, because it has a complete meaning

Step 1: Check if 'A bird is sitting on the fan.' starts with a capital letter. Yes, 'A' is a capital letter. Step 2: Now check if it gives a complete meaning. It tells us WHO (a bird) and WHAT (is sitting on the fan) — that is complete! Step 3: The length of a sentence does not matter — it just needs to make complete sense. Step 4: The other options say 'No', but they are all wrong because this group of words is indeed a proper sentence. Step 5: So, yes, it is a sentence!

They are eating noodles.

Step 1: Read each option carefully. Step 2: 'eating noodles' does not tell us WHO is eating — it is incomplete. Step 3: 'They eating noodles' is missing a helping word ('are') and does not make full sense. Step 4: 'are eating they noodles' has words in the wrong order and is jumbled. Step 5: 'They are eating noodles.' tells us WHO (They) and WHAT (are eating noodles) — it is complete and starts with a capital letter. So this is the correct answer!

The words are in the wrong order

Step 1: Read 'little a Appu was elephant' out loud. Step 2: Notice that the words are all mixed up and jumbled — they do not make sense in this order. Step 3: The correct order would be: 'Appu was a little elephant.' — now it makes perfect sense! Step 4: Having too many words is not a problem. Starting with a capital letter is actually GOOD for a sentence. A full stop is also good. Step 5: The only problem here is that the words are in the wrong order, so it does not give a complete meaning.

A complete meaning

Step 1: Remember the definition — a sentence is a group of words with a COMPLETE MEANING. Step 2: A sentence does not need to have exactly ten words — it can be short or long. Step 3: A sentence does not need a picture or a number to be a sentence. Step 4: The most important thing is that the words together give a complete thought or idea. Step 5: So, the correct answer is: a complete meaning.
