Just encountered that 得 is listed twice in NPCR chapter 15 words. Please check.

There are actually two characters that look identical. de (structural particle) and dei3 (to need, must, to have to).

not exactly.. I can see both these entries have the same meaning viz. :-
obtain/must/(complement particle)

I think it one character with two meanings or functions and also with two pronunciations.

得
de
particle = (introducing a word, phrase or clause to indicate that it is a complement. 得 de is normally preceded by a verb or an adjective.)■ 來得很早 lái de hěn zǎo = come early■ 說得大家都笑了起來 shuò de dàjiā dōu xiàole qǐlái = talk in such a way that everybody starts laughing■ 貴得很 guì de hěn = very expensive

得
děi
modal verb = have to, has to■ 時間不早了, 我們得走了。 Shíjiān bù zǎo le, wǒmen děi zǒu le. = It's quite late. We've got to go.■ 這件事怎麼辦, 我們還得想個辦法。 Zhè jiàn shì zěnme bàn, wǒmen hái děi xiǎng ge bànfǎ. = We've got to find a way of dealing with this matter

得
dé
verb = get, obtain■ 她去年英文考試得了A 。 Tā qùnián Yīngwén kǎoshì déle A. = She got A for the English examination last year.dédào 得到 = succeed in getting/obtaining

Its actually three meanings and three pronunciations. I don't think skritter database support one-to-many relationship between head words and meanings/pronunciations.

I've removed the duplicate entry--thanks!
