I have written research about silent letters in Arabic and English in APA 7 format and I'd like to know how to download it and publish it, thanks a lot.
Ideally, you would first find a publication that you think might be suitable for your research, examine their guide for authors, and then write your article according to the style used by the journal. If you've already written an article in the APA style, the worst case scenario is that there are no suitable journals using it and you'll have to rewrite it to fit whatever style the journal is using.
To find journals, you might first want to try looking up recent articles discussing similar topics and seeing what journals they have been published in. Many publisher also have a website where you can browse their journals according to theme. For example, Elsevier's service is at https://journalfinder.elsevier.com
To publish, select a relevant journal, prepare a manuscript following their guidelines, submit it for review, and address any feedback or revisions. You can also consider publishing in conferences, online platforms, or academic repositories.
