Thank you Dr. Dillon!

Yes! Dr. Dillon showed me how to use the ICE Corpus for East African English and now it's working! I just checked some of the data I collected and found that the words school and tone used as verbs cannot be confirmed by the ICE Corpus. However, in the first 60 entries there are five examples of the word rest used as a transitive verb (as in, "till transport is arranged, rest the patient "). There were no entries for the word sack used as a noun in the context of to fire someone as it says in Zuengler (1982: 116). I wonder if this is a typo by Zuengler and she actually meant used as a verb. Anyways, it's working, so I'm off and running.
