"Word send" is not grammatically correct. It would need to be "Word sent" to be past tense.
Here's why:
* Present Tense: "Send" is the form used for actions happening now.
* Past Tense: "Sent" is the form used for actions that happened in the past.
Example:
* Present Tense: I send you a message.
* Past Tense: I sent you a message yesterday.
