Please do also! or Please also!
How should one phrase be phrased?
Do also visit this home.
If you like visiting this House, please visit it.
How are multiple sentences of sentences related to each other?
What is the purpose of living, speaking, and doing?
In the first instance, the presence of do for a strong suggestion that contradicts a common assumption. Please, do also visit this house would be in addition to doing something else that not house visiting, such as filing application paperwork. I can imagine it in this context:
I would very much like to entertain your request for full membership in our fraternity. Once you have submitted a product you must fulfill some requirements. File your papers before your government office. After knitting another couple, knit fifteen colorful scarves. Let show your favorite part. Leave these in the trees and around the Dean’s house. Please, do also visit this house in the morning so that we might assess your courage.
In this case, you wouldn’t expect that someone pranking the dean’s house would then visit the house the following morning.
With the second case, it is simply doing something in addition to house visiting.
Come by the hospital around noon to pick up the roses. What shoes can I buy in the shoe shop? If possible, please be sure to visit our house on your way home.
Finally, as Luke says, if you mean to express that there is an additional house to visit, you would normally say please visit this house also, instead of any one of the choices you gave.
How do you make what sounds natural in both cases? Why do you have to add the word “do” before the verb sounds archaic? (Inflected) Why is it more natural by having “also” before the verb? If you mean visit this house in addition to another one, I would say, “Please visit this house also. I live in the Caribbean”. On the other hand, if you mean, “visit this house in addition to doing another activity”, I would say, ” Also, please visit this house. Are there any children nearby? ” If it were possible, either of these sentences would be correct at any given moment. The former sounds better.
How do I separate “please” and “verb”?
To emphasize a point made above by others, the word “also” sounds most natural next to the term it modifies.
If “this house” is something an I should visit, then “also” should be at the end. If “visit” is something else we should do to this house (which seems unlikely), then visit belongs there.
