## 12.2.8 Inflection: Pluralization and Singularization¶

- Inflections are different forms of the same words, such as singular and plural (like “person” and “people”) and different verb tenses (like “run” and “ran”)
- When you’re calculating word frequencies, you might first want to convert all inflected words to the same form for more accurate word frequencies

In [1]:

    from textblob import Word

In [2]:

    index = Word('index')

In [3]:

    index.pluralize()

Out[3]:

    'indices'

In [4]:

    cacti = Word('cacti')

In [5]:

    cacti.singularize()

Out[5]:

    'cactus'

- Pluralizing and singularizing are not as simple as adding or removing an “s” or “es” at the end of a word

In [6]:

    from textblob import TextBlob

In [7]:

    animals = TextBlob('dog cat fish bird').words

In [8]:

    animals.pluralize()

Out[8]:

    WordList(['dogs', 'cats', 'fish', 'birds'])
