“… has really caughten up….” quickly corrected to “caught up”, spoken by the therapist at the hospital. I remember we used to laugh at my aunt when she would say “putten” instead of put for the past participle.
Some of these strong verbs cause people problems b/c of the operation of analogy, e.g. I will not use the SE “sneaked” but rather “snuck”. I feel stupid saying, “They sneaked into the house.”
Others, like “lie/lay” are obviously easily confused and while it’s nice that some snoots manage to keep them straight, it is not a sign of mental deficiency to say “I laid down yesterday and took a nap”.
