蝦夷方言藻汐草

Nakagawa hoskisakne and Tamura hoski sakne mean the summer before last. NINJAL gives the joined form under おととし and also has hoski sakne pa, supporting comparison with 去々年. Its dictionary bot repeats the same material. Two 2015 newspaper examples use hoskisakne against Japanese 前年の夏, demonstrating why a fixed two-year offset cannot be inferred from every corpus occurrence. hoskiansakne refers to the summer three years back in Nakagawa and adds a syllable absent from this record; hoske sakne keeps the historical ケ vowel but lacks retrieved support.
