Pronunciation: [θˈʌmbtaks] (IPA) 
The word "thumbtacks" is spelled as /ˈθʌmˌtæks/, with the stress falling on the first syllable. The "th" sound at the beginning is followed by a vowel sound that is pronounced as "uh", represented by the symbol "ʌ" in IPA. This is followed by the "m" and "b" sounds, and the word ends with the "tacks" syllable. The spelling of this word accurately represents its pronunciation, making it easy to spell and pronounce correctly.
Thumbtacks are small, sharp-pointed fasteners commonly used to secure paper or other lightweight materials onto surfaces such as bulletin boards or walls. Also known as push pins, push tacks, or drawing pins, thumbtacks are typically made of metal, such as steel or brass, featuring a slender body with a thin, sharp point at one end and a flat, circular head at the other.
Measuring around 1 to 2 centimeters in length, thumbtacks are designed for easy insertion into various surfaces using minimal force, often requiring only thumb pressure to be pushed into place. The sharp point pierces through the material being secured, ensuring a secure hold with the use of friction. The head of a thumbtack is typically round or cylindrical, allowing for easy gripping and removal when no longer needed.
Thumbtacks find wide applications in offices, schools, homes, and other environments where temporary fastening is required. They are particularly useful for displaying notices, memos, photographs, or artwork on bulletin boards or securing paper onto walls. Additionally, they serve as handy tools for organizing charts, maps, or calendars. Thumbtacks come in various colors and finishes, providing opportunities for personalization or color-coding systems.
While thumbtacks can be convenient and efficient for affixing lightweight objects, caution must be exercised to avoid accidental pricking, particularly due to their sharp point.
The word "thumbtacks" is derived from the combination of two separate words - "thumb" and "tack".
"Thumb" originates from the Old English word "thuma", which refers to the first digit of the hand, specifically the one opposite to the four fingers. The term "thumb" has remained relatively unchanged in its meaning throughout history.
"Tack", on the other hand, has its roots in Middle English, coming from the word "tak", which means a nail or pin used for fastening or attaching things. "Tack" itself is derived from Old Norse "tak", with a similar meaning.
When combined, "thumb" and "tack" form "thumbtacks", which describes small pins or nails with a flat, wide head that can be easily pushed into objects using the thumb.
