    Does one say An LED or A LED

    Hi

    LED stands for Light Emmiting Diode.

    Is it correct to say: "A LED..."

    or

    Is it correct to say: "An LED..."

    Typically if you said the words Light Emitting Diode out in full,then one would say
    : “The voltage applied to A Light Emitting diode is…”
    But if you said LED as and abbreviation, and pronounced it 'ell eee dee', then the ‘e’ at the beginning being a vowel, would mean you would say: ”The voltage applied to AN LED is….

    just a student.
    I'd say "a led" because "led" starts with a consonant.
    this is the basic rule, right? any reason for not applying it?

    Re: Does one say An LED or A LED

    I do agree with you, but the reason I ask, is because of the way you pronounce the abbreviation LED ( 'ell eee dee') - now if it is said this way (not written...) then the word starts with a vowel, so one should use an as opposed to a.

    I am sure you are correct, it just SOUNDS funny. Perhaps one should say the words LIGHT EMITTING DIODE out in full and not say the abbreviation i.e. 'ell ee dee'?

    The only reason is that in speech it sounds awkward/wrong to say 'a ell ee dee'.

    I think 'an LED' if you pronounce it as an abbreviation. Like 'an FBI agent', 'an MP'.
    But if it is pronounced as a word then 'a LED'.

    now I see your point! it's a very good question indeed! I think a native has already answered!

    Re: Does one say An LED or A LED

    In the early 18th century, in words like history, h was not pronounced and thus there you would find the usage of an before history(an history student) or an historical moment. Thus the second sound becomes more important in usage of an.
    In this way only, the word LED has e in second place, which acquires prominence while pronouncing it. Thus, perhaps, it being an acronym, has become an exception to the rule. Else, a LED would be more appropriate.

    It's not a matter of not applying it, it's a matter of getting the wording of the rule right. The rule is Add an -n before a vowel-sound. If you frame the rules right, there are fewer 'exceptions' to learn.

    While I'm a teacher now my background is Electronics ,so I'll add my own view here. I have heard both "led" and "el ee dee" used. Whichever was used was really down to the personal preference of the speaker.

    My own personal preference was to use the spelled out L-E-D.

    Thanks BobK, that settles the matter, just one thing, can we spell it Alidee or just stick to L.E.D.
