The word 'sixth' serves a dual role in English grammar, functioning both as a noun and an adjective, depending on its application within a sentence. This versatility allows it to either name a specific position or quantity, or to describe the sequential order of another noun.
'Sixth' as a Noun
When 'sixth' acts as a noun, it typically names a position, a fraction, or an entity. This usage refers to the person or thing that comes in the sixth place or represents one of six equal parts.
- Referring to a position or rank: In this context, 'sixth' stands alone to signify the item or individual at the sixth spot.
- Example: "She proudly announced, 'I placed sixth in the competition!'" (Here, 'sixth' refers to her final rank.)
- Example: "The sixth arrived late, missing the beginning of the ceremony." (Referring to the sixth person or item in a sequence.)
- Representing a fraction: 'Sixth' can also denote one part out of six equal divisions of a whole.
- Example: "Only a sixth of the initial budget remained by the project's end." (Signifying 1/6 of a whole.)
- In specific educational contexts (e.g., UK English): While often part of the noun phrase "sixth form," 'sixth' can implicitly refer to this educational stage, especially in informal contexts, acting as a standalone noun.
- Example: "Many schools prepare students for their move up to sixth." (Referring to the 'sixth form' or the academic year itself.)
'Sixth' as an Adjective
Conversely, 'sixth' operates as an adjective when it modifies a noun, providing information about its order or sequence. In this capacity, it identifies something as the item or person immediately following the fifth and preceding the seventh.
- Describing sequential order: This is the most common adjectival use, specifying the position of a noun.
- Example: "The sixth chapter of the book delves into advanced concepts." (Modifies 'chapter'.)
- Example: "Please hand in your homework on the sixth day of the month." (Modifies 'day'.)
- Example: "He celebrated his sixth birthday with a grand party." (Modifies 'birthday'.)
- In educational terminology: 'Sixth' describes the specific 'form' or year group in educational systems, particularly in the UK.
- Example: "Students in the sixth form are preparing for university." (Modifies 'form', making 'sixth form' a specific noun phrase.)
Decoding Context for Grammatical Function
The grammatical function of 'sixth' is entirely dependent on its surrounding words and the overall meaning of the sentence. Recognizing whether it's naming something (noun) or describing something (adjective) is crucial for accurate interpretation and construction of sentences.
Ordinal Numbers and Their Versatility
'Sixth' belongs to a class of words known as ordinal numbers, which indicate position in a sequence (e.g., first, second, third). Many ordinal numbers exhibit this grammatical flexibility, serving as both adjectives (describing a noun's position) and nouns (referring to the item at that position or a fraction). For a deeper understanding of parts of speech, consider consulting reputable grammar resources like the Oxford Learner's Dictionaries or Merriam-Webster.
Summary of 'Sixth' Word Types
| Word Type | Function | Example Sentence |

| Adjective | Describes the order or sequence of a noun | This is the sixth time. The sixth floor. |
Practical Insights and Examples
- Noun usage tips:
- If you can replace 'sixth' with a pronoun like 'it' or 'them' (referring to the sixth item), it's likely a noun. For instance, "The sixth was the best" can become "It was the best."
- Often, when used as a noun, 'sixth' is preceded by an article (a, an, the), such as "a sixth" or "the sixth."
- Adjective usage tips:
- If 'sixth' comes directly before a noun and answers the question "which one?" (e.g., which attempt, which floor), it functions as an adjective.
- It will always be modifying an explicit or implied noun to provide more detail about its position.
