Fetching Single item from JSON Object

How can I fetch single item from JSON?

In this is case, I want to fetch only value of Word

How can I do that inside Expression (Without Function Node)

Here is my current code:

{
  "nodes": [
    {
      "parameters": {
        "values": {
          "string": [
            {
              "name": "webhook",
              "value": "  {\n    \"word\": \"Hello\",\n    \"definition\": \"This is Definition\",\n    \"pronunciation\": \"Haha\"\n  }"
            }
          ]
        },
        "options": {}
      },
      "name": "Set",
      "type": "n8n-nodes-base.set",
      "typeVersion": 1,
      "position": [
        840,
        290
      ]
    },
    {
      "parameters": {
        "keepOnlySet": true,
        "values": {
          "string": [
            {
              "name": "Output",
              "value": "={{$node[\"Set\"].json[\"webhook\"]}}"
            }
          ]
        },
        "options": {}
      },
      "name": "Set1",
      "type": "n8n-nodes-base.set",
      "typeVersion": 1,
      "position": [
        1040,
        290
      ]
    }
  ],
  "connections": {
    "Set": {
      "main": [
        [
          {
            "node": "Set1",
            "type": "main",
            "index": 0
          }
        ]
      ]
    }
  }
}

You have to append the key, in this case “word”:

{{ $node["Set"].json["webhook"]["word"] }}
