is LEAD a reserved word in MySQL SQL? : For this simple table, created in MySQL 8.012

CREATE TABLE `lead` (
  `ID` int(11) NOT NULL,
  `TS` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `RS` json DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

The statement
*INSERT INTO lead (ID,RS) VALUES (1397,'{"ID":"1397","TITLE":"John Lenon -TESTE ZAPIER 54","HONORIFIC":"0"}') 
ON DUPLICATE KEY UPDATE RS = VALUES(RS);*

FAILS when submitted through PhpMysqladmin with error 

Static analysis:

3 errors were found during analysis.

Unrecognized keyword. (near "ON" at position 111)
Unrecognized keyword. (near "DUPLICATE" at position 114)
Unrecognized keyword. (near "KEY" at position 124)
SQL query:

INSERT INTO lead (ID,RS) VALUES (1397,'{"ID":"1397","TITLE":"John Lenon -TESTE ZAPIER 54","HONORIFIC":"0"}') ON DUPLICATE KEY UPDATE RS = VALUES(RS)

MySQL said: Documentation

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'lead (ID,RS) VALUES (1397,'{"ID":"1397","TITLE":"John Lenon -TESTE ZAPIER 54","H' at line 1

HOWEVER, if the table name is changed, say, to "myleader", the statement works like a charm.

Any thoughts?
