Stress

It is not easy to establish exact rules for stress in English words, but there is a rule-of-thumb that might be helpful:

• In originally English words, the stress generally lies on the first syllable: ‘daily, 'maker, 'handwriting (' shows where the stress is).
  If a longer word starts with an English preposition or a syllable without real meaning like be-, the stress generally lies on the syllable after the preposition (on the stem syllable): over'come, under'stand, with'draw, be’lieve.
  ‘English words’ means words that have been part of the language from time immemorial. We find many counterparts in e.g. Danish and German: compare English daily with Danish daglig and German täglich.
• In words of foreign origin, the stress can lie almost anywhere. The crucial factor is the language from which they come, typically French and Latin: ’region, o’riginal, tempera’mental. Here the stress is imported from the original language.
• Note that cognate nouns and verbs often have a different distribution of the stress:  contri'bution : con'tribute, exami'nation : ex'amine, modifi'cation : 'modify.

Note the stress in these nouns: 'concept, i'dea, 'process.
