Waffle Words

Welcome to the world of Waffle Words. This is not an edible waffle but a waffle filled with letters. You have to create lines to form words. You can create horizontal, vertical or L-shaped lines. Note that you can't create diagonal ones. You will get a score based on total combined number of points over the letters that you use. The words are available in 6 languages (including English). Can you find the longest possible word? How about the word with the highest score?
