> The one-worded “ahold” often goes with the verb “get” and the preposition “of,” as in “Get ahold of yourself!” You could also say, “I grabbed ahold of his arm” to mean “I grasped his arm.” Dictionary.com (1) calls the word “ahold” informal, but it’s been around since 1600 or 1610. As for the two words “a hold,” you could say, “He’s got a hold on me” or “I put a hold on that library book.”
