@James it happens to us all it is not always helpful when trying to set a good example to learners.
getting computers and algorithms to understand language is much more difficult than it was first envisaged. The best we have done so far is to have fast instantaneous pre recorded scripts that trick us into believing a machine is speaking to us/with us like a human.
@ Richard I was hoping to get one or more teachers to comment on the use of "have showed" and/or to give an example when it might be acceptable.
"have shown" as always been or mostly been the way it was taught, but "have showed" in a sentence is creeping in and an internet dictionary search showed "have shown" to be correct by all accept two that said "have showed" is now acceptable and beginning to be used.
Pleased your dwellings are now spick and spam and in a tidy state.
You have indeed shown us what you did lately, but you haven't used any of the words show, shown, showed, showing. You score marks for showing us = telling us in writing. I cannot deduct marks from a reliable person as you, can you give an explanation us to how you have shown us in grammatical terms even though you have not used the word "show" in any tense.
