How to find out wether a word exists in english using nltk

Question

I am looking for a proper solution to this question. This question has been asked many times before and i didnt find a single answer that suited. I need to use a corpus in N

Answer 1

Based on my experience, found two options with NTLK:

1:

from nltk.corpus import words

unknown_word = []

if token not in words.words():    
    unknown_word.append(token)

2:

from nltk.corpus import wordnet

unknown_word = []

if len(wordnet.synsets(token)) == 0:    
    unknown_word.append(token)

Performance of option 2 is better. More relevant word got capture in option 2.

I will recommended to go for option 2.
