update type and clear errors to accurately describe what is 'typeable' or 'clearable' (#1651)

* update `type` and `clear` errors to accurately describe what is 'typeable' or 'clearable'

* newly built assertion for example.spec from 1.0.1 update

* 'the' to 'a' - reads better in err message

* update specs to reflect type change in err msg.
