It's all the stuff you bung into a sentence or a string of sentences: the words, the punctuation, their relationships to one another and the grammatical rules which govern them. Thanks again, Peter!

Bonjour, Sophie. Je suis heureux vous l'ai apprécié. Merci.

Hi, I am a student at St. Paul’s and I am doing a project on Mythology. I was wondering if I could use your picture of Hyacinthus? Thanks!

Hi, Eleanor. You're welcome to use Hyacinthus. Please give Coxsoft Art a credit and a link. If you click on the white-beard at the bottom of my home page, it will take you to my Award page. Click Winners and look for a link to Classical Mythology. It's a great educational website which will do half your work for you. Piccies too. Best of luck on your project.
