点滴（てんてき、tenてki）
- intravenous drip

The Japanese word 点滴 (てんてき, *tenteki*) primarily refers to intravenous infusion or IV drip. It's a medical procedure where fluids, medications, or nutrients are administered directly into a patient's vein. The word itself describes the way the fluid enters the body – drop by drop. The substance administered is usually a saline solution, a glucose solution, or a combination of these, sometimes with added medications. The procedure is vital for patients who cannot take oral medication, are dehydrated, or need immediate medication. The device used to administer 点滴 is also often referred to as 点滴.

⚫︎ 点滴が必要な患者さん Translation: Patients who need an IV drip. ⚫︎ 高熱で点滴を受けました。 Translation: I received an IV drip because I had a high fever. ⚫︎ 点滴の準備をしています。 Translation: They are preparing the IV drip.

You would use 点滴 when discussing medical procedures or when talking about a patient's treatment. It's common in conversations related to hospitals, clinics, and medical care. If you are describing receiving an IV drip, using 点滴 is appropriate. It is also used to describe administering the treatment or the equipment used. You can use it both formally and informally, but it's most common in medical contexts.

点滴 is primarily written using kanji and hiragana. The kanji 点 means "point" or "drop," while 滴 means "drop." The reading of the combined word is てんてき. It's rare to see it written in katakana. There are no variations in the okurigana for this word. The kanji combination is the standard form and has no alternative writing methods in common usage. Variations of [点滴] itself would be a conjugation of verb form, or the similar words.

There aren't direct antonyms for 点滴. The opposite concept would involve alternative methods of fluid or medication administration, such as: ⚫︎ Oral medication.

This etymology clearly reflects the action of the procedure, as it involves the "dropping" of fluid, drop by drop, into the vein. It highlights the mechanism of fluid administration, making it a fitting description of the medical intervention.
