I am preparing a column containing 'Comments/narrative' (string) for a word cloud data set. I have a list of 209 specific words i'd like to remove from the column ('A', 'AN', 'THE', etc).
I'd rather not use the 'find and replace' recipe, for obvious reasons.
Can anyone recommend a more efficient solution? Thank you!

From the example words it seems the focus is on the so-called 'stop-words'. If so, an option would be to use a Prepare recipe and apply the 'Simplify text' processor. Enable the 'Clear stop words' checkbox. There is a tutorial about this in the documentation: https://knowledge.dataiku.com/latest/ml-analytics/nlp/concept-text-data-cleaning.html
If you want to build your own specific solution, there are some Python packages that can be of use, such as NLTK or Gensim.
