Outgrabe: Humpty Dumpty says "'outgribing' is something between bellowing and whistling, with a kind of sneeze in the middle". Carroll's book appendices suggest it is the past tense of the verb to 'outgribe', connected with the old verb to 'grike' or 'shrike', which derived 'shriek' and 'creak' and hence 'squeak'.
verb (used with object), shunned, shun·ning. to keep away from (a place, person, object, etc.), from motives of dislike, caution, etc.; take pains to avoid.
