Shakespeare would have used the full word "give" in his writing.
Here are some examples of how Shakespeare would have used "give" in his plays:
* "Give me a kiss." (Instead of "Gi' me a kiss.")
* "Give her the letter." (Instead of "Gi' her the letter.")
* "Give us this day our daily bread." (Instead of "Gi' us this day our daily bread.")
If you come across "gi" in a Shakespearean text, it's likely a modern interpretation or a mistake.
