Time to take a closer look at the stain on the floor where we normally park our vehicle . This can mean a lot depending on the color of the stain.
Clear liquids could be from the airconditioning drainage system and that is normal but if its oily then it might be refrigerant leakage so that requires immediate action.
Redish or pinkish liquid can be power steering or transmission system leakage.
Greenish or bluish or yellowish liquid might be coolant leakage ( have you noticed a drop in coolant level recently ?)
Sometimes placing a newspaper spread beneath the vehicle can help catch a leaking component or system culprit .
As a rule of thumb please check all fluid levels occasionally .
All the best of luck
