Count the number of times a particular word appears in every nth column

[Roxyz72]

I have a text-based dataset that follows strict patterns. I want to see how many times a particular word - "Noun", for example - appears in every 5th cell for each row. "Noun" also appears in other cells that I don't want to include in the count, or I'd use COUNTIF for each row. Also, other words may appear in the cell (e.g. "Verb"), which I will count later, once I've figured out the formula. Each row starts in A column, but I started the array in C column because that's where the first instance of "Noun" that I want could be, so I figured I should count from there. I tried the following:
{=SUM(--(MOD(COLUMN($C2:$PC2),5)="Noun"),--($C2:$PC2="Noun"))}
but it seems to count all of the instances of "Noun" in that particular row, while
{=SUMPRODUCT((MOD(COLUMN(C2:PC2),5)="Noun")*($C2:$PC2))}
didn't work at all. I've tried several other variations as well, too many to write down here (those were just the most recent), but none of them returns the correct value.
In one sentence: I'd like to count all of the times that the word "Noun" appears in every 5th cell of each row in the dataset.
Any help would be appreciated.

How about

=COUNT(FILTER(COLUMN(C2:PC2),(C2:PC2="noun")*(MOD(COLUMN($C2:$PC2),5)=3)))

How does that have any bearing on what the OP asked?

How about

=COUNT(FILTER(COLUMN(C2:PC2),(C2:PC2="noun")*(MOD(COLUMN($C2:$PC2),5)=3)))

Seems to work perfectly - I thought it should be a COUNT function, but everywhere I looked online said COUNT couldn't be used with every nth cell. Thanks for this!

You're welcome & thanks for the feedback.

You're welcome & thanks for the feedback.

One quick question - I get everything in the formula except the "=3" at the end, which has me a bit bewildered. Could you explain that a bit for me?

Because you want every 5th column starting at col C (3) you need the modulus to equal 3

Marvelous! Wish someone on other websites had explained that little detail. Thanks again!
