A simple and clear grammar explanation of the sentence about lions and lionesses having or not having fluffy manes, designed for young learners aged 7.
Let's look at the sentence: "Only lions have a fluffy mane; lionesses don’t."
This sentence is made up of two parts connected by a semicolon (;), which is like a strong comma used to join two related ideas.
First part: "Only lions have a fluffy mane". This means that among lions and lionesses, it is just the lions (the males) that have a soft, fluffy hair around their heads called a "mane." The word "only" tells us it is just lions, and not lionesses.
Second part: "lionesses don’t." Here, "dont" means "do not," and it is short for saying "lionesses don't have a fluffy mane." Because the first part said "have a fluffy mane," the second part just says "don't" to avoid repeating the same words again. This is called using a contraction and an implied verb to make the sentence shorter.
Overall, the sentence is correct and clear. It nicely explains that male lions have manes, but female lions (lionesses) do not.
