Unless the naming convention were written in the 90s and all variable must follow a precise algorithm to be made of only abbreviation and a maximum length of 15.

Or for some, if it contains the value of a column in the db, it must have the same name as the column.

So yeah, instead of "UsualQuantityOrder", you get "UslQtyOrd" or "I_U_Q_O"... And you must maintain the comments to explain what the field is supposed to contain.
