I have very large list of english words (about 380000 words) in the form of a text file and the list is divided into batches of 100 words where each word is in its own line.

Your task is to examine each word and pick those words that can be considered keywords and copy that word to another text file and thus create another list of keywords which will be the deliverable for this project and write the corresponding batch number for each batch in your deliverable list.

For example given the following list:
(231)
prey
prey's
preyed
preyer
preying
preys
price
price's
priced
priceless
prices
pricey
pricier
priciest
pricing
prick
pricked
pricking
prickle
prickle's
prickled
prickles
pricklier
prickliest
prickling
prickly
pricks
pricy
pride
pride's
prided
prides
priding
pried
prier
pries
priest
priest's
priestess

Your output from above would be like this:

(231)
prey
price
priceless
pricey
pride
prickle
priest
priestess

Basically you will avoid stem words or plurals or other similar variations as well as avoiding adult oriented words. As you can see there is some smartness is required that will make you to choose both priest and priestess.
You should have very good access to internet as well excellent command of the English language because for some keyword you would need to online search on a major retailer search engine to see if it produces good results.
This is not a programming project. No programming skills are required.
I will retain full ownership of the project deliverable.

Please note the list contains about 38000 words! So it can take one full week of full time work and probably longer to complete. Please do not bid if you cannot spend a lot time and be able to work within budget. There are 379 batches and each batch contain 100 words so you can multiply the number of minutes you take for one batch by 379 to estimate the total time and divide the total by 60 to estimate number of hours.

I need only a single person to work on the project and not a team. No subcontracting would be allowed and the person communicating with me would be the one working on the project.

Here are the first 2 sample batches.
