Thân thiện

A student sharpens a lead pencil before starting a math test.

Definition

Noun: A writing instrument, typically cylindrical, that uses a solid core of graphite (often historically and colloquially referred to as "lead") as its marking substance. The graphite core is usually encased in a wooden shaft.

Usage

A "lead pencil" is a common tool for writing, drawing, or sketching. The term specifically distinguishes it from other types of pencils, such as colored pencils or grease pencils, by its core material. - For the exam, you must use a lead pencil to fill in the answer sheet. - The artist made a preliminary sketch with a soft lead pencil.

Advanced Usage

• The term "lead pencil" is a historical reference, as the marking material is graphite, not actual lead. This usage persists in common language.
• In technical or artistic contexts, one might specify the hardness of the graphite (e.g., 2B, HB) within a lead pencil.

Variants and Related Words

• Pencil (n): The more general term for the instrument. "Lead pencil" is a specific type of pencil.
• Graphite Pencil (n): A more technically accurate synonym for "lead pencil."
• Mechanical Pencil (n): A pencil that uses a replaceable, mechanically advanced graphite lead, often in a plastic or metal casing.

Synonyms

Notes

• The phrase "lead pencil" is itself a compound noun. The core word for this entry is the complete compound "lead pencil," referring to the specific object.
• Do not confuse with the separate words "lead" (the metal) and "pencil" used independently.
