In the aerodrome environment there are a number transmissions which are clearances but which the OP may not consider as a clearance because they don't include a "clear" word. These may include: taxi, RWY crossing and line up. A "clear" word is only used in association with a take off or landing for obvious reasons.
Whilst here I have a query on overseas practice. In YouTube clips and sound bites, I hear controllers clearing an aircraft for takeoff followed by the wind or some other information. In Australia, "cleared for takeoff" must not be followed by anything else except a turn direction with a visual departure.
Are the YouTube clips correct or is it bad practice?
