What are four letter words starting with the letter i and ending with the letter d?

Answer 1

The only four-letter words in common English are the abbreviation IBID (for ibidem, same text location), ICED, and the brand name IPOD.

ANS2:

Acronyms often become full-fledged words (see link) so, you'll need to see the rules to verify that they are permitted. Here is a pretty exhaustive list that the unscrambler provides (see link).

1. ibid, as above

2. ibrd, International Bank for Reconstruction and Development

3. iced, To have added ice.

4. Icod (de los Vinos): City in the Canary Islands

5. igad, Intergovernmental Authority on Development

6. imid, Immune Mediated Inflammatory Disorders

7. inbd, abbr for Inbound or International Next Business Day

8. ipid, Intermittent Peripheral Infusion Device (intravenous catheterization)

9. iPod, as above

10. ired, Infrared Emitting Diode or (possibly) having raised somebody's ire

11. irid, abbr for iridescent

12. ised, Institute of Social and Economic Development or (possibly) to have tried to justify a lie by questioning the definition of a word in the accusation (see link): "It depends on what the meaning of the word 'is' is..." I'd give you that in a Scrabble game.
