if i do something bi-weekly, that means every 2 weeks. just like a tricycle has three wheels, and a unicycle has just one. but, if semi-annually means twice in a year, why does a semi-truck have 18 wheels??

Semi- is a prefix from the Latin language meaning 1/2. The Greek equivalent is hemi-. Examples: *Semicircle = an arc equal to 1/2 circle*Semiquaver = Canadian term for a sixteenth note (An eighth note is a quaver)*Semicentennial = 50th anniversary
A semi-trailer is a trailer without a front axle. A large proportion of its weight is supported either by a road tractor or by a detachable front axle assembly known as a dolly. A semi-trailer is normally equipped with legs which can be lowered to support it when it is uncoupled.
A semi-trailer truck or tractor-trailer (colloquially known as an 18-wheeler, semi, or big-rig in the US, as a semi in Australia, US, and Canada, and as an articulated lorry, artic, or truck and trailer in the UK, Ireland, and New Zealand) is an articulated truck or lorry consisting of a towing engine (tractor in the US, prime mover in Australia, "truck" in the UK and New Zealand), and a trailer that carries the freight. In the UK, the term juggernaut is sometimes used for especially large articulated lorries, whilst the term 'semi-trailer' is almost unknown.

beacause at its root: semi means a half or part of something
so, a "semi-truck" is two halves, the truck and the trailer.

"Semi-truck" has nothing to do with the wheels. It has TWO PARTS! :-D

usually semi means half. so if you do something semi annually, you do it every half a year.
