Why we are consider the channel length modulation as a mosfet second order effect

This in MOSFET is caused by the increase in depletion layer width at the drain as the drain voltage is increased. This leads to a shorter channel length(reduced by ) and increased drain current. ... This effect can be included in saturation current as : Here is calledchannel length modulation coefficient.
