Lexicalized version of "IF"

 

---

Conditional IF:
Suppose I sign, "TOMORROW RAIN? PICNIC CANCELLED."  During the "tomorrow rain" portion of the sentence I raise my eyebrows and tilt my head forward (yes/no question expression).  Then I nod my head once while signing "picnic cancel."   --This would be an example of an "implied if."  This "implied if" is based on a condition, (for example: rain).  If then condition is true, then the second part of the sentence will happen.
