Search for entire word only when using string.includes() in Javascript

I am trying to search whether a string is present inside an array of strings using the string.includes() method as shown below 

var theString = "clovers are the best";
var theArray = ["lovers", "loved", "clove", "love", "clovers"];
for (i = 0; i < theArray.length; i += 1) {
  if (theString.includes(theArray[i])) {
    console.log(theArray[i]);
  }
}

The output I get includes "lovers", "clove" and "love" in addition to the expected "clovers." How can I force the search to look for entire string only?

It's returning the extras because they are a part of "clovers". My recommendation would be to split the string individual words: 

var input = prompt("enter string").split(" ");
unallowed=",.()[]{}-_=+!@#$%^&*~`|\\<>?/\"':;"; //list of not allowed chars
for(i=0; i<input.length; i++)
{
    for(j=0;j<unallowed.length;j++)
    {
        input[i]=input[i].split(unallowed[j]);
        if(typeof(input[i])=="object")
            input[i]=input[i].join("");
    }
    
}
var theArray = ["lovers", "loved", "clove", "love", "clovers"];
for (i = 0; i < theArray.length; i += 1) {
  for(j=0; j<input.length; j++)
      if (input[j].toLowerCase()==theArray[i]) {
        console.log(theArray[i]);
  }
}
edit: fixed a few derps in my code.

You're testing each element of the array to see if the element is present in the string. You can just test the array to see if a particular string is a member, which is closer to your description of the problem.

    var theString = "clovers";
    var theArray = ["lovers", "loved", "clove", "love", "clovers"];
    var idx = theArray.findIndex( e => e === theString );
    console.log(idx);
    // finding a string done two ways
    idx = theArray.indexOf( theString );
    console.log(idx);

If idx is not -1, the string is present in the array
