Correct spelling, explanation: supplement comes from Latin word supplēmentum with original meaning that by which anything is made full. It first appeared in English around XIV century. Supplement can be a noun or a verb and is composed of three syllables sup-ple-ment. We should remember about double p” to keep the right spelling. Shortened version supliment is not correct.

Definition of supplement:
noun, an addition that completes or makes up for a deficiency;
John works out very hard and takes sports supplements to gain more effects.
– an appendix to a publication that supplies information;
We need to work on the supplement for the next edition of our dictionary.
– in geometry: an arc that when added to another arc forms a semicircle;
Marie had to do additional math homework to fully understand the idea of supplement in geometry.
verb, to supply a deficiency, etc.;
A doctor ordered her to supply her vitamin deficiencies with appropriate medicaments.

Incorrect spelling, explanation: although supliment can be easier to pronounce this is not the correct version of the word supplement. Correct spelling does not consist of the letter i, as the letter was not a part of the original Latin ancestor supplēmentum. In the contemporary word supplement, we should also not forget about double consonant p.
