"Show," "shown," and "showed"

I need advice on the best use of the verb show.

When do you use showed? I find myself substituting has shown, even when I meant to use the preterit in my sentence.

I prefer "she has shown" over "she has showed"; are there differences in phrasal verbs, such as "show up" or "show out"?

Do you ever use "shew" and its family?

Solution 1:

Do you ever use "shew" and its family ?

No.

When do you use "showed" ?

When you need the simple past tense.

Last week I showed you how to cook apple pie.

Solution 2:

Show vs shew from the Google NGram viewer

Solution 3:

The rules of phrasal verbs apply the same for "show" as any other verb. To use "show up" using past perfect, you'd say "she has shown up" just like if you were saying "she has shown" but with "up" added afterwards.

You don't use "she has showed". If you mean to imply that the event happened earlier than another event in the same sentence, you'd use "she had shown" rather than "she has showed." An example of this would be "She had shown us her collection of stamps when we asked." You might hear "she has showed" but it is incorrect English.
