Use of Capital letters and Number formats
Capitalization Rules
Capitalization is the use of an uppercase letter for the first letter of a word and lowercase for the remaining
letters. The general rules of use are as under:
A sentence always begins with a capital letter
Capital letters are used for headings in reports, articles, newsletters, and other documents
Capital letters are used for titles of books, magazines, and movies
Capitalize the first word, and all other important words in a heading or title (conjunctions and
prepositions are normally not capitalized). Example: The Lion and the Mouse
Proper nouns must always be capitalized. Examples: Dr. Prasad is my physician. I love South Indian
food.
Capitalize the name of months, days, cities, states, and countries. Examples: January, Monday, New
Delhi, India, Maharashtra.
Some abbreviations use capital letters. Examples: NDTV, ATM, HTML
Capitalize titles that come before personal names. Examples: Ms., Dr., Officer-in- Charge, Col.
Capitalize abbreviations for academic degrees and other professional designations that follow
names. Examples: M. Radhakrishnan, PhD.
Do not capitalize seasons. Examples: winter, spring, summer
Writing Numbers
There are rules for expressing numbers as figures or words. General guidelines for writing numbers
include:
Numbers one through nine should be spelled out with words. Numerals should be used for the
number ten and anything greater. Examples: One clerk and three workers were needed to form a
team. The teacher placed an order for 35 notebooks.
Use words for numbers that are indefinite or approximate. Examples: About fifty people offered to
donate blood. There were approximately ten thousand new cases of H1NI last year.
When a number begins a sentence, it should be spelled out. Example: Thirty copies of the report
should be made.
When two numbers come together in a sentence, use words for one of the numbers. Example:
There are 9 thirty-year-old people in my team.
Use words to express fractions. A hyphen comes between each word. Example: The owner offered
one-half of the sales proceeds for the day to his employees.
When expressing time, use numerals followed by a.m. and p.m. designations. Always spell out the
number that appears before the term “o’clock”. A colon is used between numerals expressing hours
and minutes, but is omitted when using the 24-hour system. Examples: 2:30 p.m.; eight o’clock; 16:00
hrs.; 1345
Use numerals for days and years in dates. Do not write “th”, “nd”, “rd”, or “st” after a number.
Examples: I started my journey on March 24, 2017. I quit my job on January 2, 2017.
