In some pages, NVDA repeats the word clickable several times before saying what the clickable item is. Something like: "clickable clickable clickable clickable clickable clickable clickable clickable click here to begin."
For example: go to my.snhu.edu. From the top of the page, press f to go to the next form field.
NVDA uses the word "clickable" eight times in the course of saying I landed on an edit box that is titled: "search this site." This is, I am sure, because of bad web design, but NVDA should cope with this and not say the word "clickable" more than once per item, and never for form controls, at least, it seems obvious that a button or text field is clickable, this is how one interacts with them.

Edit
Since I am not able to reproduce this via snhu.edu site, consider the following example (paste into the address bar in Firefox or Chrome):
data:text/html,<p>text before the clickable div</p><div onClick=";"><div onClick=";">This is some text before the button <br /><button>foo</button></div> bar</div><p>This is the paragraph</p>

• After NVDA reads out "text before the clickable div"
• Press f to jump to the button.

Actual behaviour:

Chrome

clickable
foo
button

Firefox

clickable
clickable
foo
button
