The base form of the verb is also called the dictionary form. We'll give you one guess as to why.
This form is the starting point: you can change a base verb into all of the other forms of verb. It's more flexible than our yoga instructor.
"Jordan's dad makes her practice her clarinet in the garage."
Practice is the base form of the verb that means to perform an action habitually. While Jordan practices her instrument, her dad practices running to the opposite side of the house and turning up the TV as loud as possible.
"The Scottsdale Magpies play in the Northern Tasmanian Football Association."
Those devils! Play is the base form of the verb that, in this example, means to take part in a game.
"I smell smoke. Is your backpack on fire?"
In this example, smell is the base form of the verb that means to perceive the odor of something through your nose via your olfactory nerves. (Yeah, we can describe things fancily.) Did you know that your nose is essentially your body's air conditioner? It warms the air, humidifies the air, and costs a lot to fix.
