Usage notes
    
The prefix tri- is mainly used in the names of chemical compounds, e.g. trikloorifluorimetaani or in words that have been loaned from other languages with the tri- prefix already there, e.g. trigonometria, trikolori. For other words, the prefix kolmi-, which is derived from the Finnish word kolme (“three”) is preferred.
